Hi, there!
I'm a new usser of the CFX 10.0. I'm working at EADS Aerodynamics Department. And I'd like to know how can I get the CD with CFX 10.0. Or I'd like to know how can I do it with Ensight 8.0, thanks! |

Hi...I think you ahve to know the drag force, dynamic pressure and reference area to calculate the drag coefficient. You can calculate dynamic pressure as = 0.5*density*velocity*velocity and Reference area depends on the geometric model. CFX witll give you drag force value. Go to POST, Load the result file, click the calculator, choose "force", select the direction of drag (x,y or z), choose the surface of the geometry on which drag has to be calculated and thats it. click "calculate". It will give the drag value... Regards, VVJ.

Hi Klaas, feeling very happy to be your friend. You said your problem is to reduce the drag on a rotating wheel. Can you please elaborate on rotating wheel. Is there any friction or something? With the drag value on this wheel, what further studies will be done? Please let me know. Regards, VVJ.

well i try to determine the lowest drag in form and there is no other friction then air so it must be in the form and the ideal in differant angle´s
as well a disc wheel as a spoked wheel we are talking about a bike wheel |

Hi Klaas, I have not worked on form drag problems. I dont have much knowledge in this problem. Anyhow , I will work on this after some time. Presently I have exams. I will mail you again. Regards, VVJ
