Natural Convection in a Differentially Heated Cavity with a Heated and Cooled Circular Cylinders

Published: 18 May 2020 Publication History

Abstract

In this paper, the LBM method is used to simulate the natural convective flow and thermal behaviors of air inside a differentially heated cavity containing two inner circular cylinders maintained at different temperatures. Several configurations namely Bh -- TC, BB -- Th, Mh -- MC and MC -- Mh corresponding to different possible arrangements of the two cylinders inside the cavity were analyzed. The results are presented in the form of streamlines and isotherms for a selected range of the Rayleigh number Ra (103-106). The obtained results show that the arrangement of the cylinders inside the cavity considerably affects the flow structure in the cavity.
