Abstract

The goal of this study is to look into how a mixed nanofluid moves between two permeable tubes when thermal radiation and heat are present. The finite difference method is used to get the exact answers. Graphs and tables show how the amount of nanoparticles, the porous material, radiation, heat production, and angular frequency affect the speed, temperature, and Nusselt number. The nanofluid made of TiO2 and water had the fastest speed, while the nanofluid made of TiO2 and water had the widest temperature range.
