Ritz_physics is on a distinguished road
Hey everyone!

I am currently working on improving natural draft cooling tower efficiency. My finding from a research paper is that just above drift eliminators, the air velocities across the transverse section of the tower are such that the velocity of air is higher near the periphery of the tower, than in the center. In the research paper, it was mentioned that this is because of the hyperbolic shape of the tower.
In addition, I referred to another paper in which the cfd modeling of the tower was illustrated and it further proved this fact. I thereby want to develop a "mathematical relationship" that links air velocity to the hyperbolic shape as well as demonstrates that the velocity should decrease as we move radially inward across the tower section. So, how do i start with this modeling? Could you please refer me to a literature that explains how this type of modeling is done?
