Numerical solution of heat and mass impulse transfer problems

Conclusion To solve special classes of stationary and nonstationary two-dimensional problems of momentum, heat, and mass transfer, we developed various packages of applied programs which, after the introduction of specific data, corresponding to a specific statement of the problem, and the development of their program provide its numerical solution. The use of fully implicit approximation methods and of direct solution of the linearized equations provides the possibility of developing effective numerical algorithms, making it possible to obtain the solution in a wide region of Reynolds and Rayleigh numbers.These methods can also be used for numerical investigation of transport processes in turbulent flows and in rheological media. In principle, they can be generalized to solving three-dimensional problems. In this case, however, for a small value of the grid step the number of equations becomes very large, and high-power computers are needed to realize these methods.Translated from German into Russian by E.
