Abstract

PURPOSE: To sharply increase the maximum efficiency than the conventional one equipped with a nozzle not having guides-blades by arranging a number of grooves placing an angle to the circumferential direction, on the wall surface of the nozzle part not having guide blades.
CONSTITUTION: On the wall surface of the nozzle part 4 of a turbine casing 1, a number of grooves 5 placing an angle corresponding to the angle of conventional guide blades to the circumferential direction are arranged, so the gas flow in the vicinity of the wall surface 5 forms a flow along the groove 5, and also in the vicinity of the center of the nozzle part 4, the gas flow is affected by the flow in the vicinity of the wall surface 5 to some extent, and the flow at the inlet 7 of the vane wheel is equalized, and the maximum efficiency sharply increases in comparison to the conventional one not having guide vanes, and also the high efficiency range is wider than that of the one having guide vanes, and the harmony with an engine increases, and the engine torque characteristic is improved.
