NUMERICAL MODELING OF 3D WIND VELOCITY FIELD IN THE ATMOSPHERE
Keywords:
mathematical model, wind speed, Navier-Stokes equations, finite-difference method, solution approximation, run-through methodAbstract
As it is known the distribution of harmful substances in the atmosphere directly depends on the wind speed. This paper considers the problem of hydrodynamics in the form of nonlinear partial differential equations of Navier-Stokes to determine the velocity of air masses in the atmosphere in three directions u, v and w. The wind speed at each point of the considered region is different. Therefore, in this paper we have developed an algorithm for the numerical solution of the equations of atmospheric air mass velocity in three-dimensional space with respect to time and space variables, using a high-order approximation and an implicit difference scheme to ensure the stability of the computational process.
