Workshop

CFD Solvers for Unsteady Marine Applications: Capabilities and Challenges

December 13th and 14th, 2007, Trondheim

Organized by CeSOS

Background

The objective is to collect people among the worldwide most outstanding researchers involved in the development of CFD solvers and their application within the marine field. The emphasis is on violent unsteady free surface/interface flow and blunt-body flow separation problems.

A wide variety of problems of interest are characterized by violent unsteady free-surface/interface flows (i.e. bow, bottom and stern slamming events with and without air entrapment phenomena; water shipping; sloshing in internal tanks) or involvement of blunt-body type flow separation (i.e. ship maneuvering, vortex induced vibration for marine risers and pipelines). Such complex phenomena are generally rather challenging and represent a prolific applicaton field for Computational Fluid Dynamic solvers. The fast development of computational resources has motivated an increasing research effort in this direction.

The present workshop is aimed to offer (1) the unique oportunity to learn the features of the major CFD methods from the researchers who either developed or contributed strongly to their improvement and establishment and (2) the chance to discuss the state-of-the-art CFD applications in the marine field, with emphasis on both the capabilities and limitations experienced .
