Modeling of turbulent fluid motion based on the boussinesq hypothesis. Overview

A mathematical simulation of a turbulent flow in a compressible and incompressible viscous fluid is consi-dered using the example of the simplest model of turbulent motion, obtained as a result of averaging the Navi-er—Stokes equations from Reynolds and Favre in conjunction with the Boussinesq hypothesis on the presence of turbulent viscosity. Algorithms for averaging the Navier—Stokes equations for a compressible and incom-pressible fluid are given. Appropriate equations for the averaged and pulsating field parameters for incompress-ible and compressible liquids are given. The results obtained are useful in the design of a new type of radiator, described in [1, 2], when operating in the turbulent regime of fluid motion.
