This work presents the results of numerical modeling Karman vortex street generation performed with ANSYS/FLUENT package application. The influence mechanical elements located downstream bluff body on frequency has been found during earlier laboratory investigations. Five various geometrical configurations have tested. Considerable differences in pictures distributions pressure, horizontal and ...

Abstract

The mean flow and turbulence statistics of the through a simplified urban environment, which is an active research area in order to improve knowledge turbulent cities, investigated. This useful for civil engineering, pedestrian comfort health concerns caused by pollutant spreading. In this work, we provide analysis obtained from well-resolved large-eddy simulations (LES). A detailed database re...

We study the behavior of an elastic loop embedded in a flowing soap film. This deformable loop is wetted into the film and is held fixed at a single point against the oncoming flow. We interpret this system as a two-dimensional flexible body interacting in a two-dimensional flow. This coupled fluid-structure system shows bistability, with both stationary and oscillatory states. In its stationar...
