A fundamental study of the flow past a circular cylinder using Abaqus/CFD

چکیده
Abstract: The latest release of Abaqus version 6.10 includes Abaqus/CFD. The inclusion of this software makes it possible for users to perform a fluid analysis in a more user-friendly manner. Independent single software solely for CFD is currently available from many developers, and many attempts have been made to link software of CFD to structural analysis system using some specific procedures such as fluid structure interfaces (FSI). Direct implementation of CFD in FE structural analysis software offers ease of access to CFD. Adopting the position of a mechanical engineer trying to use CFD for the first time, a series of fundamental analyses were performed using Abaqus/CFD. Fluid flow around a circular cylinder placed in a uniform flow was investigated in addition to the occurrence of various phenomena associated with von Karman vortices and the oscillation of a circular cylinder excited by these vortices over the object.

متن کاملHybrid CFD/BEM Approach to Predict Flow Induced Noise
A computational approach is proposed to extract the acoustic sources generated by low Mach number flow past a circular cylinder and to predict the associated far-field acoustic pressure. The transient hydrodynamic flow field is calculated using an incompressible computational fluid dynamics (CFD) solver. The acoustic sources are extracted from the hydrodynamic flow field based on the linearised...
متن کاملEffects Of Frequency Variation At Inlet Flow On The Vortex Shedding Frequency Behind A Circular Cylinder
In many applications the flow that past bluff bodies has frequency nature (oscillated) and it is not uniform. This kind of flow has effects on the formation of vortex shedding behind bluff bodies. In this paper the flow around a circular cylinder was numerically simulated. The effects of frequency variation at inlet flow on the vortex shedding frequency were investigated. The transient Two-Dime...

متن کاملEvolving strategies for active flow control
About fourty years ago – according to (Rechenberg, 1994) – Rechenberg and Schwefel came up with the idea of evolution strategies for flow optimization. Since then advances in computer architectures and numerical algorithms have greatly decreased computational costs of realistic flow simulations, and today Computational Fluid Dynamics (CFD) is complementing flow experiments as a key guiding tool...
