A COMPARATIVE STUDY OF TWO AND THREE DIMENSIONAL LOW REYNOLDS NUMBER FLOW

2차원 및 3차원 저레이놀즈수 유동 해석 비교 연구

In this study, two and three dimensional low Reynolds number flows are compared. For the two dimensional flow, an airfoil was considered and for the three dimensional low wing and full-body aircraft were considered. Because a flight condition of the aircraft is in a low Reynolds number flow, itl requires reflecting flow transition. In the two dimensional analysis, transition is predicted using en method. In the three dimensional flow, the effect of transition is included using k-w SST turbulence models.
