• The behaviour of the characteristic solution in the neighbourhood of the firstfrozen Mach line is investigated for the two-dimensional steady supersonic flowof a non-equilibrium gas along a curved wall. We assume that the gas is in non-equilibrium with a finite reaction rate and various transport effects are negligible.It is found that when the wall is a continuous curved bend, the first spatial deriva-tives of gas properties at the first frozen Mach line depend on the relaxationlength and the curvature of the wall shape at the beginning of the bend. Theposition of breakdown of the solution and the conditions necessary for no shockto form on the first frozen Mach line are obtained. For a concave wall with asharp corner, a frozen shock wave emanating from the corner is formed. Theshape of this frozen shock wave is also obtained. Further, the solution in thelinearized case is obtained.
