Short Review of Modeling, Analysis and Prediction of Shock Structures with Multiple Reflections of Simple Waves. Experimental and Numerical Studies

“…In [7] the process of difraction of plane shock wave on a curved body is researched experimentally. Schematic of the arising flow is presented (see Figure. 11b from [7]) which is characterised by two shear layers and a lambda-wave which is dislocated inside the area of the shear layers beginning.…”

“…Schematic of the arising flow is presented (see Figure. 11b from [7]) which is characterised by two shear layers and a lambda-wave which is dislocated inside the area of the shear layers beginning. In can be predicted that the "tail" of the lambda-shock for some Mach number is possible to be a compression wave and its interaction with these shear layers can give rise to the process of multiple reflection of simple waves.…”

“…Such type of shock structures was discovered in different problems: problems of streamlining a body by a supersonic flow containing an external energy source or in problem of interaction of plane shock wave with the boundary of heated and cold gases or in the situation of Edney IV shock/ shock interaction. In some cases of shock wave diffraction these structures haven't been obtained but prerequisites were created for obtaining these structures [7].…”

Determination of Rounded Edge Diffraction Loss for a Plateau Using Hacking Method

“…However, approximation will under-estimate the diffraction loss that can be caused by the plateau [6,7]. In that case, a rounded edge obstruction approximation is preferable [8][9][10][11][12][13][14].…”
