From the above discussions, we can get the conclusions that the heating on the water flow in a channel has a significant effect on the location of transition initiation and shifts it downstream, delaying the beginning of the turbulent flow. The local Nusselt number at the point of laminar breakdown depends on the inlet Reynolds number. In addition, the results also manifest that the local Reynolds number at the point of laminar breakdown depends on the inlet Reynolds number and the heat flux. Both the flow and heat transfer characteristics in the transition regime indicates the change of viscosity is not the dominant factor that introduces the delay of transition.
