Abstract

A new method has been used to solve the transonic flow equation for flow over a wavy wall. The results thus obtained are compared with those obtained from windtunnel experiments. A new fluctuating flow phenomenon has been observed both in the experiment and in numerical calculations which may enhance flow mixing. The numerical results also indicate that the flow becomes locally sonic for a transonic parameter value greater than 0·5, while experimental data indicate a value of 0·6363 for the transonic parameter. The classical value of transonic parameter has a value of one for the flow to become locally sonic.
