Thermal radiation effect on unsteady MHD rear stagnation point in Al2O3-Cu/H2O hybrid nanofluids

The evaluation of high thermal efficiency has garnered considerable interest in the context of the unique properties demonstrated by hybrid nanofluids. Therefore, the present study investigates the impact of heat radiation on the unsteady rear stagnation point magnetohydrodynamic (MHD) flow of hybr...
