Extract

In a number of applications, turbulent boundary layers are exposed to a gradual or rapid acceleration. As a result of this, the flow may change to a laminarised state before retransitions again to a turbulent flow. This change of state (turbulent-laminar-turbulent) can have drastic effects on a variety of engineering problems. For example it has significant effects on the heat transfer rate at a boundary over which it is flowing, the mixing of fuel and air in the scramjet combustors, the mixing process in the wake of a transonic turbine blade and hence the base drag, etc.
