In a supersonic flow with a discontinuous surface of tangential velocity, a Mach wave from a supersonic source is reflected and refracted at the discontinuous surface. According to the image method, a reflected wave is expressed by an image source and a transmitted wave by a transmitted source. Further more, the image method is applied to reflection and transmission of a Mach wave in a supersonic flow with two different boundaries: a discontinuous surface and a solid wall. a lot of image and transmitted sources are introduced in a flow field as the interference between these boundaries. A flow disturbed by an aerofoil is discribed as a function of the original sources distributed on the upper and lower surfaces of an aerofoil and their image sources. We determined numerically the effect of two boundaries on the characteristics of a lens section and so on.
