摘要
总结了螺旋流的流动特性的研究现状以及发展方向,指出目前在流速分布、压降特性以及衰减特性等方面需要进行进一步的研究。对于流速分布,需要采用先进的测速设备进行流速的测量,比如LDV和PIV。对于压降特性,在现有公式的基础上总结出应用于实际工程领域的压降模型。对于衰减特性,需要推导出精确度高的衰减公式。
The research situation and progress on flow characteristics of the spiral flow was reviewed, and the research on velocity distribution, pressure drop characteristics and attenuation characteristics was prospected. For velocity distribution, advanced equipment for velocity meas- urement should be used, such as LDV and PIV. For pressure drop characteristics, new and prac- tical model of pressure drop should be established. For attenuation characteristics, accuracy of the attenuation formulas needs to be improved.
