gn = germano_number(re,r,p,cr)
Computes the Germano number given the Reynolds number
, the helical pitch
, radius
and the curvature ratio
. The Germano number is then defined as:
Reynolds number .
Helix radius (
).
Helix pitch (
).
Curvature ratio (dimensionless)
Returns
Germano number , dimensionless.
