Was bewegt einen jungen Maschinenbauingenieur, die Barthaare (Vibrissen) von Robben zu erforschen? "Der Wissensdurst", schmunzelt Matthias Witte (32). Er hat nach seinem Studium in Rostock am Lehrstuhl für Strömungsmechanik der Universität Rostock in seiner Doktorarbeit herausgefunden, wie Robben sicher ihre Beute fangen. Mit den vorliegenden Ergebnissen zur Umströmung von Vibrissen sind die Grundlagen gelegt worden, die es Bauwerksaerodynamikern auf der ganzen Welt zukünftig erlauben werden, Hochhäuser, die bald an der 1.000 Meter Marke kratzen sollen, sicherer, komfortabler und kosteneffizienter zu gestalten.
"Matthias Witte hat den strömungsmechanischen Mechanismus eines ganz besonderen Phänomens aufgeklärt", würdigt Privatdozent Dr. Wolf Hanke.
