Cavitation has been one of the critical issues in turbomachinery operation which often causes the reduction of service life of the components. In order to predict the service life, cavitation intensity (CI) needs to be measured accurately. In this paper, several notable developments of techniques to measure CI are reviewed briefly. Those techniques can be classified into two groups, i.e. direct and indirect measurements. For the indirect technique, a method which estimates the impact load of bubble collapse by inverse analysis is particularly elaborated. For the direct technique, a method which utilizes painting technique to quantify the actual CI is specifically presented. The advantages and disadvantages of both direct and indirect techniques are also discussed.
