channel_test

channel_test, a Fortran77 code which calls channel(), which computes the time-independent flow of a viscous incompressible fluid in a 2D channel. The strength of the flow at the inlet is determined by a parameter. The desired flow profile along a line downstream is given. The task is to determine the inflow parameter that generates a flow that minimizes the difference with the given profile data.

Source Code:

• channel_test.sh, runs all the tests.
• channel_test.txt, the output file.

The program writes out "XY" (node coordinate) and "UV" (velocity component) data files for the optimized solution.

• xy.txt, grid information.
• uv.txt, velocity information.
• uv_dir.png, a PNG image of the velocity direction field.
• uv_vec.png, a PNG image of the velocity field.
