Abstract
The flow structure and thermal efficiency of a gas-droplet wall jet, injected through inclined holes into a transverse trench, is analyzed numerically. The predictions are carried out using three-dimensional RANS equations in the following ranges of two-phase flow parameters: initial droplet size d1 = 0–20 µm and their mass fraction ML1 = = 0–0.05. Gas turbulence is simulated using the model of Reynolds stress transport taking into account the two-phase character of the flow. The obtained simulation results are compared using the Eulerian and Lagrangian descriptions. The applicability of both approaches to describing the dynamics and heat transfer of a two-phase wall jet is shown.
