This research work highlights the relationship between heat transport in nanofluids and wall velocity ratios in the context of mixed convection heat transport in porous cavities. The research scrutinizes the inspiration of numerous flow variables such as Richardson number, porosity, Hartmann number, Darcy number, wall velocity ratio, nanomaterials volume fraction and Eckert number on fluid flow and heat transport performance. The governing flow expressions are tackled using the SIMPLE algorithm, and the outcomes are authenticated against prior research. The findings designate that heat transfer rates upsurge with higher values of Richardson number, Darcy number, nanomaterials volume fraction, and absolute value of wall velocity ratio, while decreasing with increasing porosity and Hartmann number.
