Abstract

Numerical simulation of the swirled air flow around a fluently heated vertical cylindrical domain was performed under the influence of gravity and Coriolis forces. Solutions were obtained for the complete system of Navier-Stokes equations with constant coefficients of viscosity and thermal conductivity; together with initial and boundary conditions, they describe complicated nonstationary three-dimensional flows of compressible heat conducting gas. All gasdynamic parameters (density, temperature, and three components of gas velocity for various moments of time at the initial stage of air flow formation) are calculated with explicit-difference schema. Instantaneous streamlines corresponding to trajectories of particles in appearing flow were plotted. A negative swirling of air flow during heating of the vertical cylindrical domain was established.
