Graduate student Olaf van Campenhout explored the mechanisms behind the known beneficial effect of dimples in a surface for aerodynamics and liquid dynamics.

He used two state-of-the-art techniques, Particle Image Velocimetry (PIV) and Particle Image Surface Flow Visualization (PISFV). This sonnet by Jeroen Manders tries to grasp the essence of his thesis.
A dimpled golfball flies a longer streak,
we have known of this for quite a while
and it will make most any golfer smile,
whillst aerodynamic theorists turn bleak.
We know it does, but why we don’t yet see:
The way it works is covered in mystique.
But now, to grasp some more of the technique
there’s PIV ànd PISFV!
Two ways that show to us very precise
just in what ways all those small flows do flow;
Old theories can now be cast aside!
The benefits can be of megasize
for cars, trains, planes, pipes and… oh, I don’t know…
Let all things have a skin with cellulite!
Bauke Steenhuisen (universiteit docent bij de faculteit TBM) en Jeroen Manders (zanger, acteur, tekstschrijver, componist en voormalig IO student) verdichtten tussen december 2014 en maart 2017 42 keer een Delftse afstudeerscriptie of proefschrift tot een sonnet. Illustraties waren van Ella Nitters.
