ABSTRACT
The computational analysis of laminar mixed convection nanofluid flow has been conducted in a two-dimensional rhombus-shaped enclosure featuring a protective cover and a centrally heated cool obstacle. This study primarily focused on assessing the effects of copper nanoparticles dispersed in water as the base fluid, specifically addressing the topic of nanofluids. The temperature discrepancy produced on by the opposing motion of the enclosure’s top and bottom walls the top wall being cold and the bottom wall being cold as well will be essentially propels this mixed convection. The opposing wall is heated, whereas the opposite wall is unheated. The study evaluates whether streamlines, isotherms, velocity profiles, dimensionless temperature, average Nusselt numbers, and average fluid temperature have been affected by the Richardson and Darcy numbers, among other variables. The results indicate that both the Richardson and Darcy numbers exhibit an important effect on the system’s flow patterns and the distribution of temperatures. Furthermore, regulating heat transfer in fluid flow via the porous material inside an enclosure hinge entirely on the Darcy number. The study provides a heat transfer correlation for the average Nusselt number while also taking into consideration various Darcy & Richardson parameters.
