During certain operating conditions in spark-ignited direct injection engines (GDI), the injected fuel will be superheated and begin to rapidly vaporize. Fast vaporization can beneficial for fuel–oxidizer mixing subsequent combustion, but it poses risk of spray collapse. In this work, collapse is numerically investigated a single hole G eight-hole injector an engine combustion network (ECN). Re...

picFoam is a fully kinetic electrostatic Particle-in-Cell(PIC) solver, including Monte Carlo Collisions(MCC), for non-equilibrium plasma research in the open-source framework of OpenFOAM. The solver's modular design, based on same principles used OpenFOAM, makes it highly flexible, by allowing user to choose different methods at run time, and extendable, building upon templated classes. impleme...

Reactive transport modeling has established itself as a key player to analyze sophisticated hydro-geochemical interactions that occur over spatiotemporal scales on par with subsurface applications. In this paper, we benchmarked new reactive package—porousMedia4Foam at the continuum scale considering complex and well-established cases available in community. porousMedia4Foam was born by successf...

We numerically study gravity’s effect on sloshing in a two-dimensional tank which is highly filled by water (95% and 5% air). Both fluids are considered to be incompressible inviscid. The surface tension phase change neglected. OpenFOAM software used for the simulation. A standing wave of impacting lid at its center symmetric wetted region starts advance along lid. simulation carried out (only ...

Numerical simulation of various structures multiphase flow in the pipe was performed using OpenFOAM software package. A visual comparison design for separated stratified-wave, plug and annular modes with experimental data is presented. For modelling solver compressibleInterFoam used. From results numerical modelling, it follows that package allows correct prediction depending on Reynolds number...

Solution of large sparse linear systems is frequently the most time consuming operation in computational fluid dynamics simulations. Improving the scalability of this operation is likely to have significant impact on the overall scalability of application. In this white paper we show scalability results up to a thousand cores for a new algorithm devised to solve large sparse linear systems. We ...

Laser assisted ablation technology is widely used for micro-fabrication of metal and semiconductor components in the electronic industry. The outcome of those processes strongly depends on several variables such as the used material and different laser parameters. For a better understanding of these processes a study on the effect of the pulse length based on multi-physical simulations was perf...
