With increased flood risk due to climate change, population expansion and urbanisation; robust waterway design management are critical. One common type of used gather transport ground water is the open channel. Most simulations do not account for physical roughness bed, instead using a coefficient. This means that only turbulent energy content can be modelled whilst eddies vortices cannot. Furt...

CFD simulations of near-ground gas dispersion depend significantly on the accuracy wind field. When simulating fields with conventional RANS turbulence models, velocity and profiles specified as inlet boundary conditions change rapidly in approach flow region. As a result, when hazardous materials are released, extent areas is calculated based an that differs from defined. To solve this problem...

Following the growing interest that we observe in use of OpenFOAM for nuclear reactor analysis, current work presents a point-kinetics model and associated open-source code can easily be integrated existing thermal–hydraulic solvers to streamline multi-physics investigations. As proof concept, have new solver GeN-Foam multiphysics platform, validated it against past experimental measurements fr...
