Abstract
Results of a numerical analysis of the transition from steady to oscillatory laminar flow in gravitational convection of an incompressible fluid in a closed cavity heated from the side are presented for various Grashof and Prandtl numbers. The influence of the nonlinear dependence of convective flow on the Prandtl number on the flow structure and its temperature and concentration stratification is demonstrated.
