Modular Method for Estimation of Velocity and Temperature Profiles in High-Speed Boundary Layers

What is it about?

The accurate prediction of boundary layer properties is an essential aspect of aerospace design. In the current work, we propose an improvement to existing methods, that can be used to estimate the skin friction, heat transfer and boundary layer profiles of velocity and temperature at a given Mach number, Reynolds number and wall thermal condition. The proposed method is computationally cheap and significantly improves the accuracy of predictions, as compared to the state-of-the-art in the field.

Why is it important?

The method can be helpful in accelerating the design stage of supersonic/hypersonic vehicles by providing a better initial guess of the flow properties. Additionally, the predictions can also be used to initialize computational studies on canonical turbulent flows with more confidence.
