Experimental Investigation of an Incident Shock-Induced Interaction near an Expansion Corner; February(1) Flow Investigation of Linear Cluster Plug Nozzle; (8) December(1) Experimental study of unsteady wake effect on a film-cooled pitchwise-curved surface; October(3). The basic physical principles of the diffraction shock wave phenomenon have been widely studied around sharp corners in the range from small angles to near [1–3]. The ﬂow features that characterise the diffraction region, schematically illustrated in Figure1, are the planar incident shock wave, its weakened.

Emphasis is on the regime of moderate compression that can be produced by high-velocity impact or detonation of chemical explosives. In this regime relatively simple equations of state are applicable to the description of compression.3/5(1).
