The 23rd Numerical Towing Tank Symposium is organised by the University of Duisburg-Essen, Institute of Ship Technology, Ocean Engineering and Transport Systems. This conference focuses on the numerical simulation of flows around ships and offshore structures, with a strong link to realistic applications.
The objective of the event is to provide a forum for informal discussions among experts in the field and to disseminate latest results. Younger engineers and Ph.D. students are especially encouraged to participate.


  • Nonlinear flows around marine structures (LES, RANSE, Euler with or/w/o free surface)
  • Multiphase flows in the maritime context
  • Fluid-Structure Interaction

The conference proceedings will be made available on our website after the conference:


The event will be held at the conference hotel “Wolfsburg” in Mülheim (near Düsseldorf), Germany (
