| Abstract: | According to high-altitude and low Reynolds number aerodynamic performance requirements of a turbofan engine,the fan/compressor on 0 km and 21 km operating conditions were simulated using three-dimensional(3-D) numerical simulation software Numeca.The results show that: the three-dimensional numerical simulation results of the 4-stage fan are in good agreement with the experimental results,and the precision can meet the engineering requirements;from 0 km to 21 km altitude,the inlet blade chord Reynolds numb... |
