Shaft power matching analysis of air wave ejector
摘要
Abstract
Shaft power is an important parameter to be considered when the runoff air wave ejector is running.The relationship of structure and operation parameters with shaft power is analyzed by numerical simulation,and the optimal parameters are obtained.The results show that for the curved channel,the performance of the device is optimal when the fixed wall distance is 6°,the deflection distance is 16° and the medium-pressure port size is 23°.In terms of operation parameters,when the expansion ratio is 1.5,the compression ratio is 1.15,and the rotational speed is 3 250 r/min,the output shaft power of the device is only 453 W,the ejection rate is 66％,and the isentropic efficiency is 73％.Compared with structure and operation parameters,the channel form of the runoff air wave ejector has a more important influence on the performance of the device.For the inclined channel,when the inclination angle is 60°,the output shaft power is 730 W,the ejection rate is 134％,and the isentropic efficiency is 78％,indicating good performance.The calculated data have important guiding significance for the optimization and design of the runoff air wave ejector.关键词
