Temperature profile of a power law fluid flowing over a moving wall with arbitrary injection suction and internal heat generation absorption

The heat transfer of a non-Newtonian power-law fluid flowing over a moving surface was investigated by applying a uniform suction/injection velocity pro?le. The ?ow is in?uenced by internal heat generation/absorption. The energy equation was solved at a constant surface temperature, and the Merk–Chao series was applied to obtain a set of ordinary differential equations instead of a complicated partial differential equation. The effects of fluid type, suction/injection, and heat source/sink parameters on heat transfer were also determined. Results showed that the thermal boundary layers of pseudoplastic fluids are thicker than that of dilatants. The thickness of a thermal boundary layer increases when injection flow exists because more flow penetrates into the fluid. Internal energy generation also leads to an increase in such thickness.
