The design of crest walls is often based on empirical formulations, physical model tests, numerical models and a fair amount expert judgement. present work validates the prediction wave induced forces front face top composite breakwaters in OpenFOAM. results show that OpenFOAM able to capture shape order magnitude force events caused by non-breaking heavily breaking waves. In addition, calibrat...

Droplet (fluid) -droplet (fluid) interaction: A numerical investigation of binary droplet collisions in a gaseous phase has been conducted as part of the coalescence modeling project. A volume of fluid (VOF) based interface capturing method, which is characterized by introducing an extra artificial compression term into the volume-fraction transport equation, is employed to capture the liquid-g...

An adaptive mesh refinement (AMR) method based on discretization matrix metric is described. The computational algorithm is implemented using OpenFOAM parallel library. This open C++ library provides data structures and routines to work with the finite volume method and adaptive mesh. The method was used for oil flow in final drive simulation. For more efficient use of computing resources, we d...

The solution procedure for two phases in OpenFOAM suffers from unphysical velocity oscillations at the free surface between phases. It is likely that this problem also exists other two-phase Computational Fluid Dynamics (CFD) codes. We aim to solve by imposing boundary conditions directly on surface. have taken first step towards a new method addressing water phase alone. modelling based mergin...
