Babinsky and John K Harvey Shock wave–boundary-layer interactions (SBLIs) occur when a shock wave and a boundary layer converge and, since both can be found in almost every supersonic flow, these interactions are commonplace The most obvious way for them to arise is for an externally generated shock wave to impinge onto a surface on which there is a boundary layer However, these interactions also can be... 60 (b) Figure 2.9 (a) Type IV shock- shock interference Physical plane (b) Type IV shock- shock interference Plane of polars (M1 = 10, ϕ1 = 10◦ ) shock- polar diagram Because Type V interference is rarely encountered, this rather lengthy exercise is not undertaken here Type VI interference occurs when shocks (C1 ) and (C2 ) cross in a region where they are both weak-oblique shocks from the same family The...
