Abstract
This research work is made to demonstrate diverse characteristics of entropy generation minimization for cross nanomaterial towards a stretched surface in the presence of Lorentz’s forces. Transportation of heat is analyzed through Joule heating and radiation. Nanoliquid model consists of activation energy and Brownian movement aspects. Concentration of cross material is scrutinized by implementing zero mass flux condition. Bejan number and entropy generation (EG) rate are formulated. The employment of transformation variables reduces the PDEs into nonlinear ODEs. Bvp4c scheme is implemented to compute the computational results of nonlinear system. Velocity, temperature, and concentration are conducted for cross nanomaterial. Consequences of current physical model are presented through graphical data and in tabular form. The outcomes for Bejan number and EG rates are presented through graphical data. It is noted that EG rates and Bejan number significantly affect rate of heat-mass transport mechanisms. In addition, graphical analysis reveals that E.G. rate has diminishing trend for diffusive variable. Moreover, achieved data reveal that profiles of Bejan number boost for augmented values of radiation parameter.

Introduction
The advancement in nanotechnology and nanoscience extended the application areas for researchers and scientists. Applications of nanofluids are encouraging in different phenomena such as the heat transfer phenomena. Advancements in technology need the proficient methods for heat transfer, and nanofluids provide the more efficient medium for heat transfer from one source to another source. In addition, numerous procedures are available in the literature which can intensifies heat transport properties in flow to improve the effectiveness of concentrating collector. Nanoliquids have higher thermo-physical properties compared with those of base liquids. Moreover, nanoliquids were employed inside absorber to serve as heat transfer liquid and, therefore, boost the performance of solar system. Sheikholeslami et al.

The mass transfer phenomena is considered as an important unit of chemical process. In these phenomena, chemically reacting species (molecules) are moving from low concentrated area to high concentration. Chemical processes plays the vital role in culture and life itself. Chemical reactions are categorized in different systems due to their chemical and physical behavior, and homogeneous and heterogeneous systems are two major systems among them. Homogeneous reactions lie in the same phase space, i.e., gas, liquid, or solid spaces, while the heterogeneous reactions required more than one phase space. Khan et al. (2016b, 2017) scrutinized features chemical mechanisms for non-Newtonian fluids. Mahanthesh et al. (2017) discovered properties of vertical cone for colloidal material. Shahzad et al. (2019) reported the properties of C-matrix by employing new mathematical concept. Features of revised relation for flux and chemical processes were considered by Sohail et al. (2017). Ramesh et al. (2018) deliberated the revised conditions at boundary utilizing Maxwell nanoliquid. Irfan et al. (2018c) considered characteristics of variable conductivity and chemical processes for Carreau fluid. Tangent hyperbolic nanofluid with aspects of chemical processes and activation energy were inspected by Khan et al. (2018b). Irfan et al. (2019b) discussed the heterogeneous–homogeneous reactions for Oldroyd-B fluid.
To our knowledge, mathematical modeling for cross nanoliquid with entropy generation minimization is not yet examined. With this point of view, our concern here is to model cross nanofluid with entropy generation. Effects of viscous dissipation and thermal radiation are reported. Nanofluid modeling comprises the thermophoretic and Brownian movement aspects. Zero mass flux-type boundary condition is imposed. Idea of activation energy (AE) along with chemical reaction is also introduced. Total EG (entropy generation) rate and Bejan number are discussed for various flow variables. Numeric solutions for nonlinear systems are constructed. Nature of emerging physical is analyzed through graphs and tables.
Technical depiction and flow field equations
Our intention here is to formulate mixed convective cross nanomaterial flow towards moving surface. Moreover, we have considered magnetic field aspects for cross nanomaterial which acts normal to surface. Transportation of heat is analyzed by considering radiation and Joule heating aspects. The innovative relation of activation energy is introduced. Moreover, zero flux condition regarding nanofluid is imposed at boundary. Keeping in view the afforested assumptions, boundary layer approximation governs the following system of equations:

Authentication of our outcomes
Results
Nonlinear system subjected to conditions (11–13) is numerically tackled by employing Bvp4c scheme. Significant features of emerging physical parameters such as radiation parameter \(\left( R \right)\), magnetic parameter \(\left( M \right)\), thermophoresis parameter \(N_{\text{t}}\), local Weissenberg number \(\left( {We} \right)\), Buoyancy ratio parameter \(Nr\), Brownian motion parameter \(\left( {N_{\text{b}} } \right)\), chemical reaction parameter \(\left( \sigma \right)\), mixed convection parameter \(\left( \lambda \right)\), Prandtl parameter \((Pr)\), Eckert number \(\left( {Ec} \right)\), activation energy parameter \(\left( E \right)\), Schmidt number \(\left( {Sc} \right)\), entropy generation rate \(\left( {N_{\text{G}} } \right)\), Brinkman number \(\left( {Br} \right)\), dimensionless concentration ratio variable \(\left( {\alpha_{2} } \right)\), dimensionless temperature ratio variable \(\left( {\alpha_{1} } \right)\), and diffusive variable \(\left( L \right)\) on velocity \(f^{{^{\prime } }} \left( \eta \right)\), temperature \(\theta \left( \eta \right)\), concentration of nanomaterials \(\phi \left( \eta \right),\) Bejan number \(\left( {Br} \right)\), and entropy generation \(\left( {N_{G} } \right)\) are examined in this section. Figures 1–21 show sketched to visualize the behavior of physical parameter. Figure 1 portrays the characteristics of \({\text{We}}\) on \(f^{{^{\prime } }}\). Here, \(f^{{^{\prime } }}\) deteriorates via larger \(We\) for shear thinning liquid. Features of \(f^{{^{\prime } }}\) for varying \(Nr\) are described in Fig. 2. Larger \(Nr\) yields an augmentation in cross-nanoliquid velocity. Characteristics \(f^{{^{\prime } }}\) for varying \(\lambda\) are reported in Fig. 3. Increment in \(\lambda\) intensifies \(f^{{^{\prime } }}\). Physically, raise in \(\lambda\) yields more buoyancy forces due to which velocity of cross-liquid boosts. Impact of \(M\) against \(f^{{^{\prime } }}\) is considered in Fig. 4. Here, \(f^{{^{\prime } }}\) declines for higher estimation of \(M\). Velocity of cross nanoliquid is much higher in case of hydrodynamic when compared to hydromagnetic situation. This behavior of cross nanoliquid for hydromagnetic situation occur, because augmentation in \(M\) creates strong Lorentz force. Figure 5 demonstrates the aspects of \(Ec\) for \(\theta\). Here, \(\theta\) intensifies for larger \(Ec\). Physically, greater values of \(Ec\) produce more heat due to temperature of cross-nanoliquid enhances. Attribute of \(Pr\) on \(\theta\) is displayed in Fig. 6. Here, \(\theta\) declines for greater \(Pr\). Mathematical point of view \(Pr\) has inverse relation with thermal diffusivity. Therefore, greater \(Pr\) deteriorates significantly the temperature of cross nanoliquid. The curve of \(Nt\) for \(\theta\) is presented in Fig. 7. Clearly, larger \(Nt\) yields higher \(\theta .\) Actually, temperature difference between wall and at infinity rises due to temperature of cross-nanoliquid enhances. Nanofluid temperature upon \(R\) is illustrated through Fig. 8. An increment in \(R\) intensifies the nanoliquid temperature. Higher estimations of \(R\) produce more heat to working liquid. Figure 9 shows sketched to scrutinize the impact of \(\sigma\) on \(\phi\). Increment in \(\sigma\) deaccelerates the nanoparticles’ volume fraction \(\phi\). Figure 10 portrays the aspect of \(E\) for nanoparticles volume fraction. It is perceived from achieved data that term \(\exp \left( { - \tfrac{{E_{\text{a}} }}{\kappa T}} \right)\) deteriorates for greater values of \(E_{\text{a}}\). Significance of \({\text{Nt}}\) and \(Nb\) is emphasized in Figs. 11 and 12. For higher estimation, \(Nt\) corresponds to enhancement in \(\phi\), while opposite behavior is captured for \(Nb\). Actually, due to temperature difference between walls, nanoparticles are from higher temperature region to lower temperature region.
Entropy generation rate and Bejan number
Figures 13 and 14 explain significant features of \(Br\) on \(N_{\text{G}}\) and \(Be.\) It is perceived that greater \(Br\) leads to an enrichment in the rate of entropy generation. Mathematically, \(Br\) has inverse relation to \({\text{Be}}\). Consequently, \(Be\) deteriorate, while opposite trend is detected for \(N_{\text{G}}\). Behavior of \(L\) for rate of entropy generation \(N_{\text{G}}\) is disclosed through Fig. 15. This figure elaborates reduction \(N_{G}\) subjected to \(L\). Figures 16 and 17 sketch to interpret the attribute of \(M\) for \(N_{\text{G}}\) and \(Be.\) Here, \(N_{\text{G}}\) intensifies and \(Be\) deteriorates subjected to higher \(M\). Such a growth in \(N_{\text{G}}\) is perceived because resistance to motion of cross nanoliquid rises when \(M\) is enlarged. Figure 18 exhibits variation of \(\alpha_{1}\) versus \(N_{\text{G}}\). Clearly, \(N_{\text{G}}\) intensifies subjected to higher \(\alpha_{1}\). Figure 19 describes \(\alpha_{2}\) influence on \(N_{\text{G}}\). It is perceived from achieved data that \(N_{\text{G}}\) rises for larger \(\alpha_{2}\). Figures 20 and 21 sketch to demonstrate effect of \(R\) on \(N_{\text{G}}\) and \(Be.\) \(N_{\text{G}}\) and \(Be\) are augmented via larger \(R\).
Characteristics of surface drag force and heat transfer rate
This subsection demonstrates the features of \(M\), \(\lambda\) and \(We\) on surface drag force via Table 2. We perceived that surface drag force boosts via larger \({\text{Nr}}\) for \(n < 1\). Moreover, it is scrutinized that surface drag force decline via larger \(M\), \(\lambda\), and \(We\) for both \(n < 1\) and \(n > 1\). Table 3 elaborates the influence of numerous rheological parameters on heat transfer rate. Clearly, heat transfer rate rises for increments in \(Pr\) and \(R\), while decays for higher \(Ec\) and \(N_{\text{t}}\).
Conclusions
Here, mixed convective cross-nanoliquid flow containing magnetohydrodynamic (MHD) was scrutinized. Energy distribution of cross nanoliquid was investigated by considering Joule heating and radiation aspects. Significant outcomes prominent from whole analysis were as below.
-
Increment in local Weissenberg number deteriorates cross-liquid velocity.
-
Higher mixed convection parameter enriches the nanoliquid velocity.
-
Larger radiation parameter intensifies the liquid temperature.
-
Entropy generation boosts subjected to \(M\), \(Br\), \(R\), \(\alpha_{1}\), and \(\alpha_{2}\); however, it diminishes when \(L\) is increased.
-
Impact of \(M\) and \(R\) is reverse against Bejan number.
