| Abstract | ||
| In order to evaluate the performance of a radial turbine, its characteristics should be dttermined carefully. In turbines the flow is compressible, three-dimensional , viscous, and turbulent. The gas passages are closely spaced with blades having high aerodynamical and structural loading. The turbine characteristics need a practical determination under controlled environment so a test rig is built enclosing two basic parts, the first is for conditioning the flow passage through the turbine model, the second is for measuring the flow parameters needed to evaluate the turbine characteristics. The measured data includes the static and total pressures, the inlet and outlet temperatures, the turbine model revolutions, and the mass flow-rates of air. These data are recorded and processed using a personal computer. A theoretical study was performed in previous work in order to predict the turbine characteristics. The measured characteristics have being used to evaluate and confirm the theoretical prediction of the same turbine. | ||
