Flow across a square cylinder
WebThe flow across a square cylinder is an important test case for the validation of separated flows in the turbulent regime. In the past, it has been regularly used to validate Large Eddy Simulation (LES) models. WebAug 24, 2024 · The model is built from Plexiglas. It has a diameter D of 140mm and a span of 462mm. Circular end plates of diameter 305mm are used to minimize flow around the ends of the cylinder. These plates act to make the flow more two dimensional (though how two-dimensional is open to question). The cylinder model is mounted spanwise across …
