Hello,
I am simulating a 2-D flow over a stationary cylinder to determine the Cl and Cd over the cylinder. My question is in the lift coeff formula i.e Cl=F/(0.5*density*U^2 *Area), the area is the projected area i.e length*diameter or the surface area (2*pi*radius*length) ??? Also what values should I put for Depth, Enthalpy, Ratio of Sp. heat in the reference values tables ??? Is the depth same as diameter of the cylinder ??? |

http://en.wikipedia.org/wiki/Lift_coefficient
check especially 2d section. Formula for Lift coefficient doesn't involve Enthalpy etc.. so you are not suppose to set those parameters
