摘要

In this work, the pressure distribution was measured on the underside of a commercial valve disc (in situ) when the relief valve was subject to choked compressible flow. The results indicate the limits of three-dimensional effects on thesubstantially axisymmetric flow. The results also show the position of the minimum section (throat) and shock wave; their behaviour with changing lift is seen to match that inferred from previous work.
