Default Axisymmetric Velocity Inlet ???

Hello

I have been given volumetric flow rate Q. I would like to specify velocity inlet value "v" at the inlet of an axisymmetric simulation.

What is the value should i specify ?

If the inlet length edge length is "X"

can i calculate v as ,

v = Q / (PI*X*X)

X is the radius kind of.

or is it ...v = v/2*PI ??

I dont know if i need to specify it for 2*PI radians completely as it would be a complete 3D inlet or divided by 2*PI so that It would be for a radian slice?

Thanks

Hi Sarat,

So, Its the same value as that I would have specified for a complete 3D Simulation?

Cheers
