Lewis, S.G., Hudson, D.A. and Turnock, S.R. (2008) Improvement to body impact predictions using CFD through analysis of an unsteady boundary layer. At 11th Numerical Towing Tank Symposium. 07 - 09 Sep 2008. , pp. 65-70.

Record type: Conference or Workshop Item (Paper)


The problem of a body impacting water and subsequent settling requires an unsteady boundary layer to be modelled. In order to ensure that this boundary layer is being modelled correctly, the flow along an impulsively started flat plate moving parallel to the flow is investigated. The boundary layer on an impulsively started flat plate is well understood and is also reasonably simple to model using CFD. A commercial Naver-Stokes equations solver is used to carry out the simulation (ANSYS, 2008). The results are used to develop a methodology for generating a mesh capable of boundary layer resolution in this type of flow. A bow section impacting with water is then modelled, using the techniques developed for accurate prediction of the boundary layer.
