In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...

Smoothed Particle Hydrodynamics (SPH) is a numerical method commonly used in Computational Fluid Dynamics (CFD) to simulate complex free-surface flows. Simulations with this mesh-free particle method far exceed the capacity of a single processor. In this paper, as part of a dual-functioning code for either central processing units (CPUs) or Graphics Processor Units (GPUs), a parallelisation usi...

A computer language Java is a possible solution for the standardization of accelerator software to improve software productivity and realize common user interface. In this paper, JPP: a particle tracking code written in Java is presented as an example of Java application for accelerators. We discuss the advantage and disadvantage of developing scientific software with Java and investigate the p...

Particle-Mesh (PM) codes are still very useful tools for testing predictions of cosmological models in cases when extra high resolution is not very important. We release for public use a cosmological PM Nbody code. The code is very fast and simple. We provide a complete package of routines needed to set initial conditions, to run the code, and to analyze the results. The package allows you to s...

Inconsistency between metadata and code customizations is a major concern in modern, configurable enterprise systems. The increasing reliance on metadata, in the form of XML files, and code customizations, in the form of Java files, has led to a hybrid development platform. The expected consistency requirements between metadata and code should be checked but often are not, so current tools offe...

Particulate matter emission is one of the major air pollution problems of coal fired power plants. Though fine particles constitute a smaller fraction by weight of the total suspended particle matter in typical particle emissions, they are considered potentially hazardous to health because of their high probability of deposition in deeper parts of the respiratory tract. Electrostatic precipitat...
