研究了用缩比模型在闭环系统中模拟全尺寸轴流式空气压缩机在氟利昂中运行时的声学和气动特性的可行性。模型和原型之间的声学和气动性能的相关性。与先前发表的广义声学预测曲线一致;并开发了一种试验性声学标度律，该律允许根据模型产生的声功率级的测量值快速预测满量程声功率级。
Studies were made of the feasibility of simulating acoustical and aerodynamic characteristics of a full-scale axial-flow air compressor with a scale model operating in Freon in a closed-loop system. Correlation was attained between model and prototype for both acoustical and aerodynamic performance. Agreement was obtained with a previously published generalized acoustic prediction curve; and a tentative acoustic scaling law was developed which permits rapid prediction of full-scale sound power levels from measurements of the sound power levels produced by a model.Copyright © 1967 by ASME
