| Abstract: | The tensile strength of test liquid affects the cavitation inception numbers very seriously, and the zero-tensile strength as a criterion for detection of the cavitation inception numbers can be used, in order to reduce the influence of tensile strength. The scale effect on measuring zero-tensile strength of test liquid based on hydraulic methods must be considered. it is supposed that the zero-tensile strength can be defined by use of the comparative method, which unites the classical theory of cavitation inception with the modern one based on an identical criterion. |
