Computational Fluid Dynamics – how much is enough?

Continual improvements in CFD methods and computing resources means that CFD is now becoming a viable design-and-research tool for increasingly complex flow problems within industry.

As CFD practitioners we need to be aware of the extent to which we can rely on the data produced and to understand how much validation we still need to do. Can we just use the general-purpose commercial codes and assume the results are right? Are we sometimes too cautious? Too bold? Is it ever acceptable just to set up a CFD solution and rely on the results without validation? How far from validation cases can you go before further validation is required? Do we still need specialist niche codes in some areas? If so, which are they?

This event will focus on the key issues. A series of papers and case studies will be presented which will share best practice within the CFD users community and open debate on the extent to which we can now rely on CFD data.

The seminar will cover-
• Turbulence modelling and the relative benefits of RANS/LES approaches
• Efficient methods for boundary layer modelling
• Validation of CFD methods for multiphase flows in oil and gas applications
• CFD modelling of turbulent, combusting flows
• Customisation of commercial CFD software for complex applications
• The need for accurate boundary conditions
• Best-practice guidelines
• CFD modelling in medicine
• Microfluidic flow modelling and validation issues
• The breakdown of the Navier-Stokes equations for small-scale gaseous flows
