Implicit large eddy simulation of unsteady cloud cavitation around a plane-convex hydrofoil

LES of Partial Cavitation Around a 2D Plane-Convex Hydrofoil Large Eddy Simulation of Partial Cavitation Around a 2D Plane-Convex Hydrofoil

Investigations of attached partial cavitation are important because to prevent damages in hydrulic machinery and to reduce the costs. As expected computational fluid dynamics (CFD) methods have been developed for more than 40 years to understand this phenomenon and to improve the machinery designs, as pumps and hydraulic turbines. However, cavitation appears at high Reynolds numbers, so that, t...

Implicit Large Eddy Simulation for Unsteady Turbulent Flows

A numerical investigation of high-resolution schemes for solving the compressible Navier-Stokes equations in the context of Implicit Large Eddy Simulation (ILES) is presented. Computations have been performed using a hybrid total variation-diminishing (TVD) scheme. The hybrid TVD scheme combines third-order Godunov-type fluxes with first-order (dissipative) schemes using the flux limiters appro...

Analysis of unsteady concentration and flow statistics around an isolated building by Large-Eddy Simulation

Large-Eddy Simulation is used to simulate wind-induced pollutant dispersion from a vent on the roof of a cubical building. The profiles of the computed mean value and standard deviation of the concentration in the wake of the building are compared to wind-tunnel measurements and good agreement is found. The velocity and concentration values at two monitoring points located in the shear layer de...
