چکیده
|
The heat transfer of a non-newtonian power-law fluid flowing over a moving surface was investigated by applying a uniform suction/injection velocity profile. the flow is influenced 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.
