Flow Development and Performance Characteristics of an Axisymmetric Dual-bell Nozzle under Varying Nozzle Pressure Ratio Conditions

Dual-bell nozzles (DBNs) provide passive altitude compensation by adapting their effective expansion ratio through controlled flow separation and reattachment. In this study, the flow-regime evolution of an axisymmetric DBN is investigated numerically over a nozzle pressure ratio (NPR) range from 10 to 100. The nozzle...
