| 摘 要： | 对称翼透平的起动性能是透平设计中必须考虑的一个重要因素。本文利用单向稳态流动试验中获得的透平力系数和电机测试中获得的电机阻尼力矩特性,对对称翼透平在规则振荡流与不规则振荡流中的自起动过程进行了数字模拟以分析透平在规则与不规则波下的起动性能。计算了不同的周期、振幅(内波高)和透平转动惯量下的自起动性能,分析了这些参数对自起动性能的影响。

| Abstract: | A mathematical model was formulated to simulate the self-starting process of the wells turbine in regular and irregular oscillating air flow. Based on the turbine force coefficients and the restraint moment function of electric generator, the self-starting performance was investigated with different oscillating air flow conditions and the inertia of the turbine. The results show that the self-starting time is shortened with the increase of the amplitude of oscillating air flow or decrease of the period of oscillating air flow and the inertia of the turbine. |
