An analytical method of a three-dimensional cascade with partial cavitation in a spanwise shear flow between two parallel plane walls is presented. An equation of motion with respect to disturbance pressure is transformed into two differential equations by separation of variables. One of them is the equation of spanwise direction and the other is the equation of sectional plane of a hydrofoil. For the differential equation and boundary conditions of the spanwise direction, an existing analytical solution is adopted. The differential equation with boundary conditions of the sectional plane of the hydrofoil is reduced to a simultaneous integral equation with respect to singlarity distributions and is solved by using the analitical method previously proposed by the auther for the three-dimensional isolated hidrofoil with partial cavitation. These two kinds of solutions corresponding to individual eigenvalues are combined linearly, and numerical calculations are carried out to clarify the characteristics.
