Abstract: The flowfield equations of 2-C- D nozzle have been solved by a time-dependent finite difference method known as two step MacCormack technique. The computational results of nozzle wall pressure distribution and thrust agree with experimental data well. A complicated shock system have been attained through the computation of exhaust flow-field.
