how to calculate swirl without using swirl generators
I am working on simulation of combustion process in axial flow gas tubine combustor. The main reference journal paper has s 2-D model and no information about the swirler. They have solved for swirl number 0.37,0.76 and 1.2. The air inlet ratios are as follows
primary(axial):secondary(radial):dilution(radial) as 5:7:8. Now, I am looking forward for a method to calculate swirl. Is there any formula/method to calculate swirl in terms of velocities. I request you to help me.

Give the angle to flow components. For example V*cos and V*Sin
