The goal of this project was use LES and RANS (SST k-omega) CFD turbulence models to find the drag coefficient of a hollow cylinder at various inclinations and compare the results. The drag coefficients were evaluated for three angles relative to the flow (0, 45, and 90 degrees) and three Reynolds numbers (1000, 5000, and 10000). The drag coefficients determined by LES and RANS agreed for the 0 and 90 degree inclined hollow cylinder. For the 45 degree inclined hollow cylinder the RANS model predicted drag coefficients about 0.2 lower the drag coefficients predicted by LES.
