A laminar model for mixing in stratified flow

Abstract EN

The laminar simulation of convection in stably stratified fluid layers subjected to bottom heating and upper shear flow is presented.

The system consists of three layers stratified in a stable manner, with a dense layer at the bottom, a light layer at the top, and a stratified layer in the middle.

The top layer undergoes shear flow and the system is subjected to a constant heat flux at the bottom.

The system is simulated by solving the complete form of the 2-D laminar equations, utilizing the usual Boussinesq approximation, along with the appropriate initial and boundary conditions.

The simulation is employed to investigate the density, temperature, and velocity profiles for the three layers as they progress with time.
