For the purpose of improving the turbine performance and reducing the development period of the turbines, we tried the compressible turbulent flow analysis of the vaneless scrolls for radial turbines and mixed-flow turbines. We analyzed the single-entry and twin-entry scrolls of the radial turbines and the twin-entry scroll of the mixed-flow turbine and carried out the flow measurements of the mixed-flow turbine scroll. We applied "PHOENICS" code to these analyses. It became possible to analyze the complicated 3-dimensional flow passage of turbine scroll and to realize the flow pattern inside the scroll.
