This paper deals with Theoretical Basis of Cavitation Test for Hydrofoil Cascade. In order to obtain the accurate characteristics of hydrofoil cascade used for design of Kaplan Turbine, Axial Flow Pump and Shippropeller, the method of cavitation tests for hydrofoil cascade should be performed under the theoretical background. Usually the cascade tests are performed under the finite number of airfoils or hydrofoils arranged in the test section of the wind tunnel or cavitation tank. Therefore, the test results obtained by the above apparatus differ from the accurate characteristics of ideal cascade with infinite number of airfoils or hydrofoils. In this paper the theory of correction due to the number of airfoils or hydrofoils and due to the wall effects of test section is discussed by means of the conformal mapping, and the numerical examples of the above-shown theory are compared with the experimental results obtained in a cavitation tank, recently installed in the Hydraulic Laboratory of Kyoto University, Kyoto, Japan.
