摘要

The momentum balance model is applied to a long duct for prediction of the position of the pseudo-shock and its effectiveness is discussed. The model was previously applied to a short duct, where the downstream edge of the shock is at the edge of the duct. In a long duct, the upstream and downstream edges are separated from the duct edges, and the pseudo-shock is in the middle of the duct. The results calculated using the model are compared with experimental results. They showed reasonable agreement. The model will be effective to predict the position of the pseudo-shock even in a long duct.
