| Abstract: | The variations of the mass flow and the efficiency of an inward radial-flow turbine with twin-entry and nozzleless volute under both full admission and partial admission conditions are investigated. Experimental results are given and compared with those for radial turbine with nozzle ring. It is found that the efficiency of turbine with nozzleless volute is lower than that of a turbine with nozzle ring. However, with partial admission. the efficiency of the turbine is reasonably reduced, although little effect is exerted on the performance of the turbine with nozzleless volute when the speed is higher.This method is proposed for calculating both the efficiency and the mass flow characteristics of the turbine with twin-entry and nozzleless volute under different admissions. The results calculated are in good agreement with experimental ones. |
