Overview

This three hour free seminar provides an opportunity to learn of recent advances in the application of Computational Fluid Dynamics (CFD) to solve vortex induced vibration (VIV) and related problems running in a Windows HPC Server 2008 environment. It is intended to provide a review of our current understanding of this application and includes many recent developments not found in current texts.

The seminar begins with a brief overview of the physics of VIV and CFD methods. Special emphasis is placed on solving fluid-structure interaction such as VIV and vortex induced motion (VIM). Real world examples are used to illustrate practical considerations and also the limitations in current technology. Comparisons between CFD and experiments will be discussed along with the use of CFD to enhance or replace physical testing.
