Description

This paper introduces a design procedure for a compressor System with separately driven pre-runner and main runner. The approach is restricted to radial-line blading, generally used for high work transmission, high-volume flows, and/or for reasons of stability and technology. Initially the intended application was the compression of water vapor under a vacuum condition with a high-pressure ratio for use in an environmental friendly refrigeration plant with water as a refrigerant. The paper introduces some geometrical aspects of radialline blading. It gives an algorithm for a quick design and flow calculation of a wheel pair consisting of pre-runner and main runner, where the pre-runner is axial with curved blades and the main runner is mixed-flow with totally straight blades. A design example is shown along with examination of flow stability and design rules for such a system.
