摘要
针对航空发动机涡轮功热力分析法的不足,将计算机流场仿真与力学分析相结合,推导出了单位时间内燃气对涡轮做功的计算公式,并进行了仿真计算。结果表明,该公式不仅与燃气流场参数有关,还与涡轮转速、几何结构等有关,更适合于涡轮特性分析与结构设计。
Aiming to the deficiency of thermodynamic analysis method of aeroengine turbine work,computer flow field simulation was combined with mechanical analysis,deduced the calculation formula of work done by gas on turbine in unit time,and carried out simulation calculation.The results show that the formula is related not only to gas flow field parameters,but also to turbine speed and geometric structure.It is more suitable for turbine characteristic analysis and structural design.
