| 中文摘要 | in this paper, the method of trial manufacture of model machine which is combined with numerical simulation is taked to explore the inherent law of ultra-micro gas turbine (umgt). the main work includes the design and manufacture of ultra-micro stator and rotor, the structure design of overall system and the study on integration technique, the performance test of model machine driven by cold air and hydrogen gas respectively. the results of performance test show that the leakage of shaft end and tip clearance of rotor is more serious than that in macro scale. it is necessary to investigate the non-contacting shaft sealing and cascade flow by conducting a three-dimensional numerical simulation which could provide theoretical support for structure optimization and efficiency improvement of system. |
