Abstract: In this paper, experimental and numerical simulation methods were employed to investigate the aerodynamic performance and flow field characteristics of an independent design thrust reverser cascade of high bypass ratio turbofan engine for wide-body aircrafts. The numerical simulation was calibrated through experiments at three typical operating points of 0.18, 0.30 and 0.35 inlet Mach number. The results of the comparison between numerical simulation and experimental measurements show that the average total pressure recovery coefficient and the deviation angle of numerical simulation are in good agreement with the experimental results.
