The behaviour of fluid flowing past a RS:X Racing 66 windsurfing fin at different angles of attack was studied both computationally and experimentally. This was achieved by creating a three dimensional computational model of the fin, which was both used to produce a physical model for experimental testing, and as the basis for analysis using the fluid analysis program, OpenFOAM. The experimenta...

In this study, a three-dimensional numerical simulation of the wind flow and pollutant transport in street canyons is carried out by a new specific solver, which is developed and coupled into an open source CFD tool box, the OpenFOAM package. The new model has been applied to study the effect of roof shapes and building heights on the flow patterns and pollutant transports in the street canyons...

Large Eddy Simulations (LES) are carried out using OpenFOAM to investigate the canopy created velocity inflection in the wake development of a large wind turbine array. Simulations are performed for two cases with and without forest separately. Results of the simulations are further compared to clearly show the changes in the wake and turbulence structure due to the forest. Moreover, the actual...

The new Arbitrary Interacting Cells Algorithm (AICA) for calculating intermolecular pair forces for Molecular Dynamics (MD) on a distributed parallel computer is presented. AICA is designed to operate on geometrical domains defined by an unstructured, arbitrary polyhedral mesh, which has been spatially decomposed into irregular portions for parallelisation. It is intended for nano scale fluid m...

in this present study, volume of fluid method in openfoam open source cfd package will be extended to consider phase change phenomena with modified model due to condensation and boiling processes. this model is suitable for the case in which both unsaturated phase and saturated phase are present and for beginning boiling and condensation process needn't initial interface. both phases (liqu...
