Answer:

Turbulent flow.

Step-by-step explanation:

For the plate in the external flow the region that has highest temperature gradient near the wall is Turbulent flow.

The velocity profile of the Laminar flow is linear whereas the it is proportional to y ^(1/7). in turbulent boundary layer. The effect is related to the delay in flow separation of the boundary layer.
