Dabrowskiego 73, ABSTRACT A new stabilization procedure for solutions of the thermo- convection equations has been presented.

The procedure allow us to achieve, by using the direct method, the convergent solutions for the wide range of values for Ra and Pr numbers. On the examples of single-segmental region (and the problem formulated in the dimensionless form).

The effect of the attenuation coefficient values of the stabilization procedure on the convergence of solutions has been described.

Also, the influence of the node numbers and configuration of the differential grid nodes in the region, on the convergence and the stabilization rate of solution for various Ra and Pr...
