Work Package 4

WP4: Compressible flows & aeroacoustics

Group lead: Prof Paul Tucker

Affiliated staff: Dr Eldad Avital, Prof Shuisheng Hu, Prof Kai Luo, Prof William Jones, Prof Richard Sandberg, Prof Neil Sandham, Prof Mark Savill, Prof John Williams

Focus on high-speed flows, as mainly occurring in aerospace applications, and aerodynamically generated noise.  Dedicated compressible flow solvers used to resolve difference in scales between acoustic and flow fields.
