| Abstract: | The parameters control problem after the shock wave for over-expansion jet in the conical and profile Laval nozzle is studied by using V.N Uskov's method,i. e. differential dynamics compatibility condition, in which the calculating method of some parameters distribution behind shock wave along SW is given. By using this method, some results obtained are similar to the results of experiments. Meanwhile the positions of Mach disc are calculated for over-expansion jet. If triple configurations of stationary shocks are formed, the distributions of parameters relating to this structure are calculated and showed in the figuration. This method is able to be used to guide the parameters design for some gas dynamic equipments. |
