Case study on thermally fluidized suspension in porous enclosure: Hybrid computational analysis

Abstract

Thermal energy conformities in a porous enclosure claim many applications like transfer of thermal energy via regulators, cooling structure in turbine blades, heat exchangers performances, and energy system equipment are some prominent heated liquid stream individualities. Considering such importance we evaluate the energy untapped characteristics in the porous enclosure embedded with a T-shaped fin. In-taking free convection initiates a flow in the triangular enclosure. To examine the heat transfer in fluid suspension, we have used energy equation. The left/right walls are considered cold. The top segments of the boundary of the cavity are carried with the adiabatic condition. The flow regime is mathematically modelled. The resultant differential system is nonlinear so one cannot find an exact solution. We used the finite element method to narrate the flow in a porous triangular cavity. The impacts of flow parameters namely, Casson parameter, Rayleigh, and Darcy numbers on the Casson temperature and velocity are shown by the use of contour plots. Casson fluid velocities, both horizontal and vertical, exhibit a drop towards the Darcy number. Along the vertical line of the porous triangular cavity, Casson fluid temperature displays a direct correlation with Darcy number. The Nusselt number increases as the Ra value increases.
