how to compute the stokes number in Fluent
 

Hello,

I want to compute the stokes number in Fluent to understand the relationship between the impact efficiency and the stokes number.

However, I find out that Fluent don't provide the results of stokes number directly.

I know that we can compute this by UDF. But I don't know which macros should we choose to compute the stokes number.

Could anyone help me with this??

Many thanks.
