Abstract
En 中文
• Downstream nozzle selection criteria based on inlet Mach number established. • Self-oscillating nozzle selection determined by inlet velocity conditions. • Nozzle energy efficiency closely related to internal shock wave structure. • Downstream nozzles regulate pulsation via shock evolution and pressure gradient control. • Velocity-matched downstream nozzles achieve 38% jet impact pressure increase.
