Abstract: Abstract. Skin friction developments resulting from coaxial and noncoaxial collisions between a ReΓ0=3000 vortex ring and stationary spheres have been explored using large-eddy simulations (LES). The diameter ratio (D/d), ...

Abstract: Detailed near- and far-field acoustic measurements were conducted for two circular stepped nozzles with 30 deg and 60 deg design inclinations at over- and perfectly-expanded supersonic jet flow conditions and compared to ...
