This study intends to investigate hybrid nanofluid flow between two permeable cylinders in the presence of thermal radiation and heat generation. The numerical solutions are obtained using the finite difference method. The influence of nanoparticle fraction, porous medium, radiation, heat generation, and angular frequency on the velocity, temperature, and Nusselt number are presented using graphs and tables. It was observed that the maximum velocity was attained by TiO2/water nanofluid, whereas the highest temperature distribution is observed in TiO2-Ag/water. Furthermore, the Nusselt number of the fluid increased by 17.5%, 19.7%, and 21.7% when TiO2, TiO2-Ag, and Ag nanoparticles were added to it, respectively.
