Analytical expressions for the developments of the thermal boundary layer thickness, wall temperature, and Nusselt number were obtained for the thermal entrance region, assuming hydrodynamically forced convective flow in a channel with a locally variable blowing mass flux. When the blowing...

... enhancement gas turbine heat transfer forced convection In the area of internal cooling heat transfer, turbulators, or repeated ribs, have been widely used to promote turbulence in order to improve the convective heat transfer of the air in cooling passages. These turbulators increase the coolant...

... of the sphere, which is thrown out after stopping in the equator. Due to the strong jet flow in the equatorial zone, heat is transferred by forced convection, but diffusion is dominant for heat transfer in other zones. At low rotational velocities, the liquid film is thrown out of the equator in the form...
