A note on the transition observations on an axisymmetric body and some related fluctuating wall pressure measurements
Abstract
Boundary-layer transition on an axisymmetric body up to Reynolds number of 1,260,000 was observed by schlieren method of flow visualization developed for water tunnel use. The spectrum of the flush-mounted pressure transducer signal showed a dominant frequency to exist at transition, and further, this frequency was in close agreement with the predicted critical frequency by Smith's approximate method of transition calculation based on linear stability theory.
