Turbelence and modeling of this phenomenon are areas of professional interest, in addition to CFD and fluid-structure interaction. CFD-online is an excellent reference source for topics in CFD. I came across their Wiki and thought this might be useful. http://www.cfd-online.com/Wiki/Turbulence http://www.cfd-online.com/Wiki/Turbulence_modeling I have been concerned the turbulence models are not necessarily adequate, especially around discontinuities, e.g. obstructions in the flow field. In addition, I am interested in developments of fluid-structure interaction models, since that requires coupling CFD with FEM structural models. I'd be interested in any experiences or reference papers.
