NUMERICAL SIMULATION OF FLOWS AROUND AN AIRFOIL DURING ACCELERATED AND DECELERATED FLIGHT
R. Yamashita, The University of Tokyo, Japan
Numerical simulations are performed to analyse flows around a NACA64A006 airfoil during accelerated and decelerated flight. Computational results show that flow behaviours differ according to the flight phase. The rear shock wave during the decelerated flight persists even in subsonic regions. This leads to hysteresis phenomenon of aerodynamic forces between the accelerated and decelerated phases.
