November 2014: What can CFD do for you?

What has Computational Fluid Dynamics (CFD) done for you lately? Or more to the point - what can CFD do for you? For a brief reminder of the broad range of internal and external CFD flow applications, and for a specific external aerodynamics case study, read on.

Heroic Aircraft Design Aided by Caedium CFD

Niklas Wendel and Julia Gundert, students at Thomas-Morus-Gymnasium, Daun, Germany, recently completed a project to envisage an airliner of the future with a focus on sustainability and fuel efficiency. Their project was named HELT, translated as a German acronym for 'High Efficiency Aircraft', and is also similar to the German word 'held' which translates to 'hero' in English. During their early concept design phase they used Caedium Professional to perform Computational Fluid Dynamics (CFD) simulations to evaluate the aerodynamic efficiency of various configurations before selecting their final Blended Wing-Body (BWB) design.

Speed Up CFD with Symmetry and Cyclic Conditions

Symmetry (or planar symmetry) and cyclic (or rotational symmetry) boundary conditions for Computational Fluid Dynamics (CFD) can often save you 50% or more in simulation turnaround time. Alternatively you can use the freed up memory to run more accurate simulations with more mesh cells clustered in areas of interest. Clearly these simulations are worth considering if your model satisfies the symmetry or cyclic criteria.
