Is it that since Cd=Fd/(0.5*density*Vinf^2*Reference area) where I have set Reference area to 1m2, I'll have to multiply as follows: Cd_actual=Cd_fluent*1/Projected Area Projected area in case of sphere would be pi*r^2. |

Hi all
Kindly clarify my doubt, My aim is to calculate the cd value of a bridge deck section for a Particular RE. I am doing a 2d simualtion,.What should be my reference area and depth.. I tried with A=1 and D=1,it doesnt give the correct cd value i calculated the surface area of the deck similar to calculating area of a rectangle and substituted the corresponding depth,,is that approach right? |
