Abstract : The difficulties of computing unsteady transonic flow in multiply connected domains with a minimum of neglections and approximations have been overcome by using: individual computational grids fixed to each cascade; a novel grid-less finite difference scheme; and physically real in- and outflow boundaries. The resulting computer program is capable of computing the inviscid, plane gas-flow through stator and rotor of a turbomachine stage made up from arbitrarily shaped (thick, round-nosed) blades of arbitrary spacing, up to local Mach Numbers of 1.8.
