| 摘 要： | 自1983年开始以液体的抗拉强度作为其空化临界压强研究初生空化的比尺效应以来,该方法已得到进一步的应用和完善。本文就研究中遇到的一些问题,如关于空化灵敏度仪的校正,“零抗拉强度”的概念,试验设备中液体抗拉强度的动态变化以及在空化试验中使用该方法的技术和意义等作详细的阐述。

| Abstract: | Since the first report oh scale effect of cavitation inception with consideration of tensile strength of water was published in 1983 [1], a new technique for measuring tensile strength of liquid named by Dr. A. Keller as "Vortex-nozzle Cavitation Susceptibility Meter(CSM)" has been improved and developed through these years of usage. Some interesting concepts and techinque are discussed in this paper. For example, how to calibrate the "CSM", how to determine the "Zero Tensile Strength of a Liquid" and how to determine the incipient cavitation number with consideration of the liquid's tensile strength. |
