Velocity boundary layer: A thin layer near the wall surface in which there is a significant velocity gradient; this is known as the velocity boundary layer. Temperature boundary layer: A thin layer near the wall surface in which there is a significant temperature gradient; this is called the temperature boundary layer, or also the thermal boundary layer

Velocity boundary layer: A thin layer near the wall surface in which there is a significant velocity gradient is known as the velocity boundary layer. Temperature boundary layer: A thin layer near the wall surface in which there is a significant temperature gradient exists; this is known as the temperature boundary layer, or thermal boundary layer.
It is a thin layer of fluid that remains stationary directly against the wall, as the viscous force acting when a viscous fluid that can wet the wall passes by it causes the flow velocity of the fluid near the wall to decrease. The temperature boundary layer is a thin layer with a temperature gradient that forms near the boundary when a fluid flows over a wall, as a result of heating or cooling
