Smoothed particle hydrodynamic model - EDF
Abstract
The purpose of the project is to consolidate EDF’s recent advances in SPH in a single code, based on the open-source GPUSPH software, to make validations cases and to apply it to a real-life appropriate case. The programme will consist of the following stages (all stages will be done in 2D and 3D, applicable to the multi-GPU branch of GPUSPH and compatible with all existing GPUSPH features, such as the motion of rigid bodies, new wall boundary conditions and k-epsilon model): - Consolidating wall functions for the k-epsilon model in the branch of GPUSPH involving wall boundary conditions, from the work recently performed at EDF on Sphynx, with validations on a pipe flow and 2-D fish pass; - helping in the merging of the existing branches of GPUSPH: wall boundary conditions branch and other branches except multi-machine GPU (the latter being managed by other developers at this first stage); - implementing inlet/outlet boundary conditions in GPUSPH, following the work by EDF in Sphynx, with validations on i) a solitary wave in 2D, ii) a breaking wave in 3D, iii) a closed pipe steady flow; - improving the Crixus tool in order to make it easier to use, according to the Fellow’s needs as regards the stages detailed below; - performing a real-life 3D simulation of the flow over the EDF La Palisse dam spillway system with the following features: i) GPU or multi-GPU simulation, ii) steady flow with inlet/outlet conditions, iii) validation from EDF’s scale model data (pressure and velocity fields, discharge law). - Performing a real-life 3D simulation of a structural feature (e.g. granulometric test field, groyne field) located within river-km 1884 and 1888 of the Danube River East of Vienna, for three different characteristic steady-state discharges.
