it all depends on what you have. If you have a physical model, then you need to use a wind tunnel, but if you have a line profile (airfoil), then you might want to go to THEORY OF WING SECTIONS by Ira. H Abbot, perhaps it has one matching your airfoil.

first thank you very much.and i have a profile and get the pressure about the profile of a submarine.then i want to know: how i calculate the drag coefficient with the distribution of the pressure .

Go to C.C. Mei's book "The Applied Ocean Dynamics".

Sorry, the full name of the book is actually:
<<The Applied Dynamics of Ocean Surface Waves>> You can also look at Dean & Dalrymple book <<Water Wave Mechanics for Engineers and Scientists >>in Chapter 8, wave forces on bodies are discussed. These are all for non-viscid flows. |
