説明

In order to improve the efficiency of the generator, it is important to increase the cooling efficiency. The generator is composed of a rotor and a stator and is a grooved rotating double cylinder with grooves cut in the rotor blade axial direction. Therefore, in order to improve the cooling performance of the generator, it is necessary to elucidate the heat transfer flow characteristics due to the rotation of the heated rotor. In previous studies, it has been shown that the heat transfer coefficient of the groove surface tends to be higher than the heat transfer coefficient of the cylindrical surface, but knowledge on the change of the flow due to the heating of the inner cylinder and the temperature distribution of the flow is It is unknown. Therefore, in this research, velocity field and temperature field were visualized by PIV (Particle Image Velocimetry) and LIF (Laser Induced Fluorescence). As a result, it is suggested that the temperature distribution inside the groove measured by LIF may be related to the velocity field measurement result by PIV.
