Abstract: Based on flow analysis of jet exhausting atomization nozzle,a simplification model and calculating method are put forward to determine flow rate coefficient for jet exhausting atomization nozzle.The method considers the structure of nozzle,properties of fluid and flow state,it overcomes the shortcomings of selecting experimential values.The calculation agrees with the experiment results basically,and calculating errors are all under 3 percent.Therefore the method has wide application.
