Computational Fluid Dynamics
To assist in the optimisation of a solution to any given project, we have invested heavily in specialised Computational Fluid Dynamics software based on the industry standard Fluid 30 system to obtain a comprehensive understanding of the required geometry and calculated the best strake geometry for a VIV suppression system.
The software is an invaluable tool during the fine tuning of a VIV system design. It provides the optimal balance of drag and vortex suppression utilising the given environment data for specific projects and ensures optimum performance in any given set of environmental conditions.
We will also verify or comply with customers own strake designers to produce a bespoke system.
The analysis has been supported by wet tank and model testing including comparison with a smooth cylinder in steady current, with the behaviour test results, and forms part of a continuous programme of product development.
Our VIV suppression system function by introducing three-dimensionality into the flow. This disrupts the spanswise coherence of vortices that might be shed, leaving the wake stable and steady.
