Investigation of square cells stability in liquids with height varied thermal conductivity

V. V. Kolmychkov, O. S. Mazhorova

Abstract: The paper numerically investigates stable convective structures in non-boussinesq fluid with thermal conductivity variyng with height. The main focus of the paper is an existance and stability of square cells for different values of Prandtl number.

Keywords: Rayleigh–Bénard convection, convective stability, non-Boussinesq fluid, numerical simulation, stable planforms, rolls, hexagons, square cells, Prandtl number, non-uniform thermal conductivity.
