Wall Jet Receiver Flow Field.

摘要

The wall jet-receiver flow field was studied analytically and experimentally for two values of jet nozzle exit Reynolds number (5000and 14,000). Various distances of receiver entrance from jet nozzle exit,receiver throughflow conditions,and dimensionless receiver widths were considered. Four different flow regimes were identified,and corresponding regime maps were constructed. Potential flow,frozen vorticity,and control volume techniques were used to predict the receiver influence length,receiver pressure recovery,receiver entrance spill flow angle,and velocity profiles inside the receiver.
