Hi,

I am using ANSYS Fluent for combustion problem with swirl in 2D.

At the moment, I know the air going in the system is 15 m/s and the diameter of the duct is 0.3 m with 45 degree fins to generate swirls.

Can someone help me finding the swirl angular velocity (rad/s) that I should input in Fluent. If not, can someone tell me how swirl angular velocity is calculated in rad/s, and what information is generally need.

Thanks
