Hi Everybody,

I am descibing my problem here: I have a cylindrical closed volume(with diameter of X m, height H m) filled with water, flowing with a constant velocity (v1 m/sec) Inside of this cylidrical volume there is a concentric cylidrical tube (diameter Y m ~ X/10 m and height H m).
A water jet is acting on the cylidrical tube from a distance d m (Y<d<X) from the surface of the cylindrical tube with a velocity of V2 m/sec (V2 is greater than V1).
How to calculate the force acting on the surface of the cylindrical tube in FLUENT.

Please throw some light on my problem.

Thanks in advance
