An improved video of simulated flow dynamics behind a small rear-facing step located near the leading edge of a wing has been posted on the Deturbulator Project website. Compared to the last one, this video uses a more accurate fluid simulation engine with 19,000 grid cells and displays the velocity field in color. To see it, take your browser to www.deturbulator.org and click YouTube in the page header.
