Understanding and predicting the behavior of turbulent boundary layers is among the most challenging topics in fluid dynamics. In practice it has an impact on the design of energy-efficient vehicles such as cars, trains, airplanes and turbo-machines. At larger speeds, however, and especially when we consider vehicles operating at supersonic speeds, effects due to the compressibility of air also become important, adding an extra layer of complexity. In addition, for the flow over any practical vehicle, the effects of pressure gradient that cause either a flow acceleration or deceleration can be severe, and for strong pressure gradients can lead to separation. This project performs fundamental studies of the effects of compressibility (expressed by the Mach number), pressure gradient, and wall temperature on high-speed boundary layers where the effects of compressibility are also important. It makes a valuable and unique contribution to our knowledge of turbulent flows.
