CFD Simulation of Flowfield over a Large Protuberance on a Flat Plate at High Supersonic Mach Number

Visualization of Type IV shock–shock interference induced by a cylindrical protuberance mounted normal to a hollow cylinder

“…The protuberance-induced interference structure of Type IV has been illustrated by several investigators with a simplified sketch, as shown in Fig. 1 (Houwing et al 2001;Manokaran et al 2003). Babinsky and Harvey (2011) pointed out that the existence of a supersonic jet (SJ) is the characteristic feature of this type of shock-shock interference.…”
