Default Drag Coefficients
Posts: n/a
Hello All, My questions are in 2 parts: 1) I have been working on external flow over bluff bodies with CFX for a while, I am able to obtain good values on lift and Moments very close to Wind Tunnel Results, however Drag has proved stubbornely difficult, at higher angle of incidence, say 5 deg or more it improves remarkably, I wonder if any one has experience to share with me that may be helpful. I am using the SST with Sp. Blend factor. 2) My other question is if anyone has or know of numerical or experimental work or depository on airfoils or other bluff bodies showing the ratio of viscous force to pressure force as regards lift,drag and moment. Cheers !
