천음속 영역에서 항공기 유동해석에 미치는 난류모델의 영향 비교

다국어 초록 (Multilingual Abstract)

In this paper, we study the effect of various turbulence models by comparing the aerodynamic characteristics and the flow patterns computed for aircraft models. An in-house CFD solver, MSAPv, that solves the three dimensional RANS equations with the turbulence model equations is used. The turbulence models used in this study are the Spalart-Allmaras model, Menters k-w SST model, Coakleys q-w model, and Huang and Coakleys k-emodel. DLR-F6 WB and WBNP configurations are selected for the study. We concentrate on the separated flow pattern variations with the turbulence models at the wing-body junction and the wing-pylon junction as well as drag polar curves.
