文摘
- •
The effect of several inlet geometries on compressor performance is investigated.
- •
A tapered duct improves surge margin, isentropic efficiency and pressure ratio.
- •
A C-D nozzle improves surge margin, isentropic efficiency and noise emissions.
- •
A conv. nozzle greatly improves surge margin and noise emissions, but chokes early.
