This paper conducted a computational fluid dynamics study of bubbly jets (not bubble plumes due to pure gas injection) in crossflow explore the hydrodynamics that are still unknown. A three-dimensional model was developed, calibrated, and validated by coupling Euler–Euler two-fluid with unsteady Reynolds-averaged Navier–Stokes approach OpenFOAM. The results showed modeled void fraction, velocit...

In this paper, a CFD-based method coupling with overset grid technique is used to directly simulate the 20/20 zigzag maneuver of the fully appended ONR Tumblehome ship model. Numerical computations are carried out by our in-house CFD code naoe-FOAM-SJTU, which is developed on the open source platform OpenFOAM. The overset grid module is used to predict the ship motions with 20/20 zigzag maneuve...

The oodlesDST code is based on OpenFOAM software and performs Large Eddy Simulations of turbulent fluid flows. The code contains a number of specialized subgrid scale turbulence models and wall models. This report describes these models in sufficient detail to allow a new user of the code to make informed decisions regarding the use of these models for particular applications. An overview of th...

Cloud computing has become the ubiquitous computing and storage paradigm. It is also attractive for scientists, because they do not have to care any more for their own IT infrastructure, but can outsource it to a Cloud Service Provider of their choice. However, for the case of High-Performance Computing (HPC) in a cloud, as it is needed in simulations or for Big Data analysis, things are gettin...
