Интенсификация теплообмена в кубе с жидкостью переменной вязкости при наличии тепловыделяющего элемента

Abstract

Free convection of fluid with temperature-dependent viscosity inside a cube with porous layer in the presence of heat-generating element has been studied numerically using the finite difference method. The cavity is cooled from the side vertical boundaries with low temperature Tc, while the other walls are thermally insulated. The mathematical model has been written using non-dimensional non-primitive variables “vector potential functions - vorticity vector - temperature”. As a result, the distributions of three-dimensional temperature fields, velocity components and integral parameters of heat transfer have been shown depending on the thermophysical characteristics of the working liquid and the porous layer.
