For laminar flow past a plate, the velocity profile is a function of a single dimensionless variable, which allows the thickness of this structure to be given by five over the square root of the Reynolds number according to the Blasius formula.
One way of estimating the size of one of these structures is by integrating the momentum thickness across the exit plane, a formalism appropriately known as the momentum-integral technique. In the case of an adverse pressure gradient, but not in the case of a favorable pressure gradient, momentum loss results in the decoupling of this structure from the immersed body beyond the separation point. For laminar flow past a plate, the velocity profile is a function of a single dimensionless variable, which allows the thickness of this structure to be given by five over the square root of the Reynolds number according to the Blasius formula. The outer edge of this region is often defined as the point where the flow velocity is equal to 99% of the free stream flow velocity. For 10 points, name this structure that represents the region of a flow where viscous diffusion is important and which are divided into laminar and turbulent types.
