The theoretical study presented is concerned with predicting the flow details in the region immediately behind a slender wedge moving at supersonic speed. An asymptotic solution is obtained for the laminar near wake, which is valid in the limit as Reynolds number based on external flow properties tends to infinity, with the external Mach number held fixed. In this limit, the interior of the recirculating flow is approximately incompressible and inviscid the viscous layer is a continuous thin layer with large transverse velocity gradient and the typical velocity of the recirculating flow must be of the same order as that of the external flow, although numerically it is small.
