Влияние положения внутреннего источника периодического объемного тепловыделения на структуру конвективного течения в замкнутой двусвязной полости

Abstract

This work deals with numerical simulation of natural convection in a closed cavity with internal unit of periodical volumetric heat generation. The governing partial-differential Oberbeck-Boussinesq equations have been formulated using non-primitive variables and solved by the finite difference method. Analysis of thermal oscillation frequency, temperature difference and heater location on flow structures and heat transfer patterns has been performed. Optimal values of governing parameters illustrating the heat transfer enhancement have been defined.
