Abstract

Combined convective flow design and heat transfer efficiency are investigated in this research for variation of some pertinent parameters inside a trapezoidal device along with heat conductive solid circular block. By the implementation of the Finite element method, flow, and heat transfer behavior are presented in detail for the ranges of Reynolds number, 50 ≤ Re ≤ 200, and Hartmann number, 20 ≤ Ha ≤ 150 along with mixed convection parameter Ri = 1. Obtained results for the flow and temperature field in the considered domain are shown in terms of the streamlines and isotherms. In addition, the heat transfer rate at the bottom heated and ceiling cold wall is presented by Nu_av_. A noteworthy heat transfer augmentation is found at both heated and cold surfaces due to upper values of Re. Interestingly, the better cooling efficiency of the device is marked out for the hot wall.
