Steamking, I am sorry for posting it in two forums. I wasn't sure which one would be a more appropriate place to ask this question.
I am sorry. I acutally posted the same question in the automotive engineering forum as well, and the website says that since I attached the figure there, I cannot attach it again here. (not sure why)
Here is the link to the thread in the automotive forum, and the figure can be seen here...
Hello everyone,
I have a question regarding the accumulated drag curve shown in the figure below for the CFD simulation of external flow over an automobile. (It is written Vehicle Cd in the figure)
It can be seen in several regions that the accumulated drag curve is dropping (ie., having a...
