Dear All


Why we have to consider the fluid as moving and the designed system will be the as a stationary?

I mean in realty the system is moving while the fluid is stationary "at most cases"..

Can anybody clarify that to me please?

I think this is to get a steady velocity of the fluid as the Navier Stoke's equation is very handy in CFD, and it is based on velocity at a point in space and time. So, the only way or probably a better way is to assume the the body constant and the fluid flowing with a constant velocity.

In your case, in fairness, you should draw the sea and move the boat along it. Sounds fun. Didn't you have a law about the relativity of motion there?
