通过引入非定常尾迹诱导过渡的时间平均间歇因子的概念,提出常规过渡的起始点位置和尾迹诱导过渡起始点位置的算法,实现了对非定常尾迹影响下涡轮叶片上时间平均换热的数值模拟。结果显示,无论在叶片吸力面还是压力面,计算与实验符合均很好。
By introducing the concept of time-averaged intermittent factor of transition induced by unsteady wake, the algorithm proposed the location of starting point of conventional transition and the position of starting point of wake-induced transition, and realized the numerical simulation of time-averaged heat transfer on turbine blades under unsteady wake . The results show that both the calculated and the experimental results are good both in the suction side and the pressure side of the blade.
