Updated ... SUIKOU-2D Ver. 1.1 (April 2008)

What's new with the updated version??

1. diffusion-dispersion terms, turbulent and dispersion stresses are added in the new version of SUIKOU-2D. The dispersion terms are produced because of the non-uniformities of the fluid flow velocity in the vertical direction during the depth-averaging. The determination of these terms requires knowledge of the information in the secondary flows across the depth which is, however, usually not known a priori. These terms are frequently found to be negligible in cases such as straight channel flows. However, the dispersion terms can be very important, particularly when there are strong secondary flows, such as fluid flows through a complex domain. The diffusion terms are supposed to overcome the elevation depressions or obstacles.

2. a wetting-drying algorithms.

3. integrating TVD (total variation diminishing) and Artificial Viscosity schemes to get better numerical dissipation control. It has been proved to increase the model robustness.

4. better formulation for numerical treatment of Bed Slope Source Terms



The worked example (click image for animation):
1. Dambreak with rectangular barrier
(Currently there is problem on blogger.com to support animation)


2. Multiple blocks

Hi Dudi,
Thanks for visiting.
I wrote SUIKOU-2D code and dedicated it to Suikou-Lab (prev.job). I already transferred the codes and all copyrights there. Shall I give you a contact person?
