| Summary: | It is widely acknowledged that the dispersion of nanoparticles considerably improves the thermal conductivity of a working fluid. The current research aims to examine hybrid nanofluid flow between two concentric cylinders in the presence of thermal radiation. The flow is driven by an external pressure gradient, and a magnetic field is applied normal to the flow direction. The impact of nanoparticle concentration, magnetic parameter, radiation parameter, and pressure gradient on the velocity, temperature, and Nusselt number are analyzed. The obtained results showed that heat transfer rates of the fluid increased by 12.4%, 10.1%, and 11.3% when Ag, TiO 2 , and Ag– TiO 2 nanoparticles were added to the base fluid, respectively. |
