Art and color in the context of CFD: Towards a better engineering design

Abstract

Typically the words ‘art’ and ‘CFD’ tend to appear in the same sentence only as either ‘the art of using CFD’ or, particularly when conferences and meetings are announced, as ‘state-of- the-art’ CFD. Unquestionably in the latter context the art of good modeling is synonymous for representing reality as close as possible. Certainly this is true for both, numerical and experimental modeling. Color on the other hand is more fundamentally related with both, art and CFD. Indeed in the 1980s CFD was often nicknamed as ‘colored fluid dynamics’ as color was largely absent from experimental techniques at the time.
