Detailed Description

Profile for flow between axially moving concentric cylinders.

Profile generated between axially moving concentric cylinders. In this case, we assume the outer cylinder is stationary, and the inner cylinder is moving at speed u0. The profile is given by: $u_0 \frac{ \log( r_1/r) }{\log( r_1/r_0)}$ where: $ r_0 $ is the inner cylinder radius and $ r_1 $ is the outer cylinder radius. Note, that this assumes axisymmetry.

GRINS::ConcentricCylinderProfile::ConcentricCylinderProfile ( )

Default constructor.

Default constructor sets parameters for the profile: value = $2.0 \frac{ \log( 2.0/r) }{\log(2.0)}$
