Inviscid flows in a radial turbomachine and its performance are predicted by using a pannel method. Possibility of the method to be used for design purpose is investigated. The flows in a radial turbomachine are reasonably simulated with several off-design flow rates. The diameter ratio of the rotor and inlet and outlet vane angles are systematically changed so that performance of the machine in various designs are predicted. All the predictions are shown to be in the range of Cordier curve. On the other hand, calculated slip factors are also in good agreement with values given by an empirical formula.
