Abstract: To compare the values between the flow cavitation number and incipient cavitation number for discriminating whether the cavitation will occur at some position or configuration is usually adopted in the cavitation free design of spillways with high velocity flow. The incipient cavitation number should be generally determined by the model test in vacuum tank. But even in the preliminary design stage, the incipient cavitation number must be known to optimize the configuration.On the basis of previ... More
