DYNAMIC STALL PREDICTION WITH TRANSITION OVER AN OSCILLATING AIRFOIL
천이를 고려한 진동하는 익형의 동적 실속 예측
Abstract
A Reynolds-Averaged Navier-Stokes (RANS) code with transition prediction model is developed and the computational results on an oscillating airfoil are compared with the experimental data for OA209 airfoil. An approximated eN method that can predict transition onset points and the length of transition region is directly applied to the RANS code. The hysteresis loop in dynamic stall is compared for the computational results using transition prediction and fully turbulent models with the experimental data. Results with transition prediction show more correlation with the experimental data than the fully turbulent computation.
