Abstract
Due to the large-scale cryogenic system of the fusion device and the existence of pulse heat load, higher requirements are put forward for the adaptability and adjustability of the cryogenic system. This paper proposes an eddy current brake helium turbine structure, which can realize the rapid adjustment of the turbine through the electric current. The design and analysis of the turbine are carried out from the three core components of the flow part, the brake device and the bearing. The results show that the rated speed of impeller is 121,000 rpm and the impeller power calculated by computational fluid dynamics simulation is 5.88 kW. The performance of the eddy current brake is shown by electromagnetic simulation, and the rated braking current of 1.1 A is determined. Through the compiled bearing finite element calculation program, the bearing clearance is optimized to 30 μm, and the bearing performance is further predicted.
