Numerical simulation of the turbulent wake behind a normal flat plate
TL;DR: In this paper, the three-dimensional wake flow behind a flat plate placed normal to the free stream has been investigated by means of direct numerical simulations and the Reynolds number Re based on the homogeneous inflow velocity and the uniform width d of the plate was 750.
Journal ArticleDOI

TL;DR: In this article, the authors present a simulation of a pipeline release scenario, in which dense-phase CO2 is released from a full-bore 36-in. pipeline, and the resulting multiphase CO2 plume disperses over complex terrain, featuring hills and valleys.
Journal ArticleDOI
Vortex shedding in flow past an inclined flat plate at high incidencea)
TL;DR: In this article, the authors investigated the properties of asymmetric wake patterns behind a flat plate inclined at angles of attack 20°, 25°, and 30° by direct numerical simulations.
Journal ArticleDOI
Cellular vortex shedding behind a tapered circular cylinder
TL;DR: In this paper, a tapered circular cylinder with taper ratio 75 placed normal to the inflow has been studied and it was observed that even with a very long time sampling a discrete cellular shedding pattern prevails.
Journal ArticleDOI
Comparison of k-ε models in gaseous release and dispersion simulations using the CFD code FLACS
TL;DR: Assessment of three well-known RANS eddy viscosity models, namely, Standard k-e, Re-Normalization group (RNG) k-E and Realizable k- e, in a representative range of gas dispersion cases by comparing models’ behavior with experimental data shows promise in yielding good results in cases involving complex-geometries and dense-phase gas-releases.
