摘要

The paper presents a mathematical model of the thermal load on the aquatic environment under various operational capacities of a thermal power plant. It was solved for an incompressible fluid in a stratified medium by the Navier−Stokes and temperature equations were based on the method of splitting by physical parameters approximated by the finite volume method. The numerical solution of the system of equations was divided into four stages. At the first stage it was assumed that the momentum transfer occurs only by convection and diffusion. The intermediate velocity field was solved by the 5-step Runge−Kutta method. At the second stage, the pressure field was solved by finding the intermediate velocity field. The Poisson equation for the pressure field was solved by the Jacobi method. The third stage assumes that the transfer was carried out only by the pressure gradient. Finally, the fourth stage of the temperature equation was also solved as motion equations by the 5-step Runge−Kutta method. The algorithm was parallelized on a high-performance computer. The obtained numerical results of three-dimensional stratified turbulent flow were compared with experimental data. The basic laws of hydrothermal processes occurring in the reservoir-cooler have revealed approximately qualitatively and quantitatively.
