Abstract
Computations for the turbulent interfaces in gravity-stratified flows are conducted using a system of contiguous blocks as the computational elements. The blocks are containers of the flow properties. Salinity, temperature, vorticity, turbulence kinetic energy and dissipation rate are carried by the blocks that move in the direction of the velocity following the Lagrangian procedure. The blocks are re-generated at each time increment. The flow properties in the blocks are transferred from the initial system of blocks to the re-generated system of blocks by conserving the flow properties and their moments. This method known as the Lagrangian Block Method (LBM) was introduced in the first ICCFD conference by the authors. Further development of the method and application of the method to turbulence in gravity stratified flows are reported in this paper.
