抄録

In order to develop a diagonal inflow gas turbine with a three-dimensional airfoil impeller, an experimental investigation was carried out. For that purpose, an airfoil impeller was made on the basis of a quasi-three-dimensional design, and the internal flow field was measured in detail. It was found that the diagonal inflow turbine with a three-dimensional airfoil impeller can be operated efficiently at high specific speed, and that the velocity coefficient of the impeller is as high as that for an axial flow turbine. But the turbine performance is strongly affected by the secondary flow in the impeller, which is so strong that the low energy fluid is accumulated near the tip of impeller. It is necessary to study on determination of the optimum incidence angle by considering this secondary flow.
