History
On the occasion of the 70th anniversary of the institute, we publish here a film made by staff members of the Chair of Fluid Mechanics together with the Media Center of TU Dresden.
The soap film analogy was harnessed by Ludwig Prandtl to solve torsion problems. At the Institute of Fluid Mechanics this analogy was used in the fifties by Werner Albring and his co-workers for the analysis of potential flows. A special optical method was developed for this purpose, which the film represents.
