Investigation of convective structures near the stability threshold in non-Bousssinesq fluid. Part two — numerical simulation
The paper numerically investigates stable convective structures in a fluid with internal heat generation, variable thermal diffusion and variable kinematic viscosity (temperature and vertical coordinate dependence is considered). The first part of the paper provides theoretical analysis of Prandtl number effect on the planform selection. The second part of the paper deals with 3D numerical simulation of convective instability in finite layer of non-Boussinesq fluid. Numerical results are compared to the theoretical data provided in the part one.
