A perspective on unsteady aerodynamic force theories: from the diagnostics of global loads to that of local stress distributions

Abstract This paper reviews field-based diagnostic theories of unsteady aerodynamic forces, ranging from formulations for total force and moment to recent developments in the diagnosis of local stress distributions. We first revisit the vorticity-moment theory (Wu, AIAA J, vol. 19, 1981, 432–441) as a starting point fo...

Extreme Wall Shear Stress in High-Speed Lifting-Body Boundary Layer

Revealing the dynamics of wall shear stress in high-speed turbulent boundary layers is critical for improving the flight performance of advanced vehicles. This study investigated extreme events of wall shear stress on the windward surface of a lifting body at a freestream Mach number of 6 and a 2 deg angle of attack, u...
