Displacement thickness : It is defined as the distance by which the external potential flow is displaced outwards due to the decrease in velocity in the boundary layer.
The momentum thickness, is the distance by which a surface would have to be moved parallel to itself towards the reference plane in an inviscid fluid stream of velocity or to give the same total momentum as exists between the surface and the reference plane in a real fluid.
The definition of the momentum thickness for compressible flow is based on mass flow rate:
