Влияние внутреннего теплопроводного блока на интенсивность естественной конвекции в замкнутой дифференциально-обогреваемой полости

Abstract

This research is devoted to the numerical simulation of natural convection in a cavity with an internal heat-conducting block. The Oberbeck-Boussinesq partial differential equations written using non-primitive variables have been solved by the finite difference technique. The analysis of the influence of the inner body geometry and the Rayleigh number on the flow structure and heat transfer has been carried out. The optimal values of the control parameters illustrating the heat transfer enhancement have been defined.
