Abstract : The steady inviscid flow through a radial compressor is computed by solving the 3-D Euler equations on both a H-type and O-type grid. The centered finite volume method with an explicit integration scheme is used to solve the equations. The numerical programmes were developed as a tool in the design process of new, high pressure radial compressors, with complex geometries and spitterblades. Special emphasis is placed on transonic compressors, and the capability of predicting complex three-dimensional flows is demonstrated. Preliminary experience using Euler solver in design work is described with the future developments expected on this subject.
