Title: IAHR Smooth Channel Test Case

By: S Semin - CHAM Development Team

Purpose of the Calculations:

Flow and Computational Details:

The main features of the problem are:

           y(x) = +/- [tanh(2 - 30*x/Re) - tanh(2)]/2 for 0 ≤ x ≤ Re/3

           u = (3/2)*(1 - y*y) for x = 0 and -1 ≤ y ≤ 1,

           v = 0.

This setup is available in PHOENICS' case library as Case B580.
