After a brief review of some recent advances in the study of the inviscid nonequilibrium gasdynamics and of the linear nonequilibrium flow equations, a small disturbance solution is obtained for a dissociated diatomic gas flowing around a striaght two-dimensional corner. The analysis is based on a small disturbance technique in which small departure from free stream conditions are assumed. Under the small disturbance approximation, the gasdynamic equation and atom mass rate equation for a dissociated diatomic gas can both be linearized. A method of superposition to solve these linearized partial differential equations is then developed through the application of the well known Greens theorem. An oxygen-like ideal dissociating gas is used as an example in calculating the flow around a straight corner in a supersonic stream. The variation of flow properties at wall condition in the relaxation zone are found and compared with Clarks solution. Author
