Abstract
A performance analysis method for a centrifugal impeller adapter to simplify performance analysis of an impeller and to obtain an accurate calculation result in comparison with analysis by way of averaging the entire flow of the centrifugal impeller. The method for measuring a flow field at an impeller exit analyzes an exit flow angle, total pressure ratio and efficiency, to enable analysis of the performance of the manufactured centrifugal impeller, wherein the flow field of the centrifugal impeller at the impeller exit is dualized into a jet region flow field and a wake region flow field, by which each flow field is sought and averaged to obtain the flow field.
