• Without slip at the wall, alternate vortex shedding occurs behind cylinder With double cylinder. Good correlation between numerical predictions and experimental results. Vortex frequency decreases as yield stress increases or inertia Viscoelastic effects are slight. Two-dimensional unsteady inertial flows of a fluid around were studied experimentally. Carbopol aqueous gels, well-known model f...

The influence of various tree planting configurations on tracer gas dispersion in an urban street canyon is studied numerically, using OpenFOAM Large Eddy Simulation (LES). A recycling and rescaling turbulent inflow generation method implemented validated against a canonical backwards-facing step case. simulations are based the CODASC experiments, where was emitted from line sources at level. e...

This paper studies Karman vortex shedding and water-level fluctuation in the inverted siphon structure of Middle Route South-to-North Water Diversion Project (MR-SNWDP) China. Field investigations numerical simulations for outlet were performed to explore characteristics hazards vortex. Numerical results compared with measured data verify effectiveness reliability model. Based on model, it is f...
