Численный расчет линий тока конвективного течения газа при кольцеобразной схеме нагрева

Numerically solved by a complete system of Navier-Stokes equations describing three-dimensional convective flow of a compressible viscous heat-conducting gas under the action of gravity with constant coefficients of viscosity and thermal conductivity. Convective gas flow is initiated by an annular heating of the underlying surface. Decisions of the full Navier-Stokes equations are constructed numerically by an explicit difference scheme in a cube with an edge length of the unit. The results of calculation and construction of the current lines, making it possible to visualize the data appearing in the conditions of a convective flow. It is shown that with increasing heating time significantly changing and streamlines showing the trajectory of motion of the gas particles in the convective flow.
