On thermally corrugated porous enclosure (TCPE) equipped with casson liquid suspension: Finite element thermal analysis

摘要

The hybrid meshed computational analysis is carried to examine the untapped partially heated ?ow fieldin corrugated enclosure. The enclosure is rooted with porous medium and equipped with non-Newtonian liquid. The ?uid ?ow is attain by considering the free convection. The uniformly heated Y-shaped fn is installed at bottom wall of cavity. Both right and left walls of enclosure are taken cold while the upper walls are carried adiabatic. The extreme triangular ribs at bottom walls are taken cold while second and third ribs are taken uniformly heated as Y-shaped fn. The ?ow fieldis mathematically formulated and solved by using Finite Element Method (FEM) in the presence of hybrid meshing. Modeling of non-Newtonian ?uid in a cavity yields Rayleigh number, Casson ?uid parameter and Darcy number. The quantities of interest includes Casson ?uid stream function, Casson ?uid temperature, horizontal Casson ?uid velocity, vertical Casson ?uid velocity and Nusselt number. Therefore, the said quantities are examined in the light of ?ow controlling parameters. The outcomes are shared with the help of stream functions, isotherms, and line graph study for horizontal and vertical velocities, and heat transfer rate. It is observed that the presence of Y-shaped fn results enhancement in heat transfer rate. Further, the variation of Casson ?uid temperature in cavity is found directly proportional to Rayleigh number.
