This is an inviscid model, we are expecting a drag coefficient of zero, and yet there is a small drag coefficient that present. We should investigate more into this.
Cd = (Cd)pressure + (Cd)skin friction
Before we can make any conclusion about the accuracy of our result, we should always make validation check. The most common validation step is grid convergence check.
