Unsteady mixed convective stagnation point flow of hybrid nanofluid in porous medium

A new kind of heat transfer fluid called hybrid nanofluid was introduced to enhance the performance of heat exchangers. The flow behavior may be investigated numerically to better comprehend the fluid features. This investigation aspires to unravel the boundary layer flow problem near the stagnation...
