Abstract:

This paper presents the numerical results of a code for computing the unsteady transonic flow in a 2D cascade of harmonically oscillating blades. The calculation of the flow field is based on an Euler code using flux vector splitting. After a description of the basic equations and the special numerical techniques applied in the code, results are presented for the first harmonics of pressure, lift and moment coefficients.
