泵及装置原型与模型水力特性换算方法

对国内外多种泵及装置原型、模型水力特性换算方法研究所取得的进展进行了回顾,主要内容包括具有奠基意义的Moody效率换算公式,考虑比尺效应的原型、模型泵及装置效率的换算方法,以及原型、模型泵能量性能参数的换算方法。详细介绍了我国学者在这方面的研究成果,并对现有不同换算方法进行了简要的评述,指出缺乏高精度完整可靠的水泵装置原型测试数据,是目前制约水力特性换算方法深入研究的重要原因,将数值模拟与理论分析和试验研究相结合,可望取得突破性的进展。

Research on Conversion Methods of Hydraulic Characteristics between Prototype and Model Pumps and Pumping Stations

A comprehensive review was made on research progress in conversion methods of hydraulic characteristics between prototype and model pumps and pumping stations, the main contents including the Moody efficiency conversion equation of milestone significance, different efficiency conversion methods between prototype and model pump and pumping system with consideration of scale effect and methods for conversion of energy parameters. The plentiful and substantial research results achieved by the Chinese scholars in this aspect were also introduced, and a brief comment was made on these different methods. It pointed out that at present lack of reliable and complete testing data of prototype pumping system with high precision is the key factor to restrict the extensive research of the subject, and a breakthrough might be made by combining numerical simulation with theoretical analyses and experiments.
