I am trying to evaluate Reynolds number in Ansys CFX 2020 R2 using CCL/Perl script on different domains in a radial turbine. But for that, I need to define the Characteristic length. So I define the diameter of the inlet, outlet, and blade based on their cross sectional area.

But, I am not sure how to define the characteristic length for volute.

Can someone help with this?
