Математическое моделирование естественной конвекции наножидкости в полости с тепловыделяющим элементом

Abstract

This work deals with numerical simulation of natural convective heat transfer of nanofluid in a square cavity with a local heater of constant heat generation flux. Analysis has been performed using 2D unsteady Oberbeck-Boussinesq equations for nanofluid and heat conduction equation for the heat-generating element. The finite difference method of the second order of accuracy has been used for numerical simulation. Effects of the heat generation strength and nanoparticles volume fraction on nanofluid flow and heat transfer have been studied.
