Stability analysis of unsteady MHD rear stagnation point flow of hybrid nanofluid

Previous studies have reported that investigating the stagnation point flow is relevant in a variety of industrial and technological processes, including extrusion and the polymer industries. Hence, the present work aims to analyse the heat transfer performance of unsteady magnetohydro-dynamics (MHD...
