Abstract

This paper presents the numerical calculation of unsteady aerodynamic forces on the vibrating cascade blade row using the implicit time integration method. It is confirmed that first and second-order Euler methods, which are the implicit methods, require less computational time than the third-order Runge-Kutta method, which is the explicit method, by two orders of magnitude.
