Abstract
AbstractThis paper presents the mathematical model of the thermal power plant in cooling pond under different meteorological conditions, which is solved by three dimensional Navier-Stokes equations and temperature equation for an incompressible fluid in a stratified medium. A numerical method based on the projection method, which divides the problem into three stages. At the first stage it is assumed that the transfer of momentum occurs only by convection and diffusion. Intermediate velocity field is solved by method of fractional steps. At the second stage, three-dimensional Poisson equation is solved by the Fourier method in combination with tridiagonal matrix method (Thomas algorithm). At the third stage it is expected that the transfer is only due to the pressure gradient. The compact scheme was used to increase the order of approximation. Then the basic laws of the hydrothermal processes depending on different hydrometeorological conditions were determined qualitatively and quantitatively approximate.KeywordsStratified mediumThermal power plantLarge eddy simulationParallel technologies
