Abstract
Pseudo-shock is often encountered in a variety of internal flows, almost always entailing an increase in total pressure loss, hence leading to deterioration of the flow system performance. This pseudo-shock is a very complex process still requiring a good deal of elucidation. In spite of the recent rapid progress that has been made in numerical computation methods, there is as yet no quantitative prediction of pseudo-shock flow. The present paper describes a simple pseudo-shock flow model using a mass-weighted averaging technique. The flow quantities across pseudo-shock were analysed for different Mach numbers, flow confinements and turbulent boundary layer Reynolds numbers. The analytical results agree well with the previous experimental data. The flow model presented can be used to estimate the important features of pseudo-shocks in engineering practice.
