Computational researchers typically work by accessing a compute resource miles from their desk. Similarly, their simulation output or other data is stored in remote terabyte data servers. VisBench is a component-based system for visualizing and analyzing this remote data. A time-varying CFD simulation of heat exchange over a louvered n provides sample data to demonstrate a workbench-oriented ve...

Intravascular stents are tubular structures placed into stenotic artery to expand the inside passage and improve blood flow. The mechanical factors affect the restenosis after stenting and image-based simulation has become a popular tool for acquiring information. The aim of this study was to demonstrate quantitatively and qualitatively the hemodynamic changes in coronary artery after stent imp...

This study focuses on modelling and simulation of horizontal moving bed/grate wood chip combustor. A standalone finite volume based 2-D steady state Euler-Euler Computational Fluid Dynamics (CFD) model was developed for packed bed combustion. Packed bed combustion of a medium scale biomass combustor, which was retrofitted from wood log to wood chip feeding for Tea drying in Sri Lanka, was evalu...

Detailed simulation of the thermal stresses of the reactor pressure vessel (RPV) wall in case of pressurized thermal shock (PTS) requires the simulation of the thermal mixing of cold high-pressure safety injection (HPI) water injected to the cold leg and flowing further to the downcomer. The simulation of the complex mixing phenomena including e.g. stratification in the cold leg and buoyancy dr...

The simulation of drop size distributions in stirred liquid-liquid systems is studied. The simulation is realized via the coupling of the CFD code FeatFlow with the population balance solver Parsival. It is shown how such a coupling may be constructed and the properties of the coupled solver are critically analyzed.

As part of the VECTIS code validation programme, CFD simulations were conducted to investigate direct-inject (DI) diesel engine combustion with the newly implemented Ricardo Two-Zone Flamelet (RTZF) combustion model. A small HSDI research engine was chosen as subject. The simulation programme consisted of 6 cases forming a complete injection time swing. CFD simulation results were compared dire...

The demand for flow visualization software stems from the popular (and growing) use of Computational Fluid Dynamics (CFD) and the increasing complexity of simulation data. CFD is popular with manufacturers as it reduces cost and the time of production relative to the expense involved in creating a real physical model. Modifications to a physical model to test new prototypes may be non-trivial a...

The development of advanced and successful numerical modelling packages for Computational Fluid Dynamics ( CFD ) within recent years has led to their widespread use in engineering and industrial environments. Increasingly this has led to a situation where package users have little or no specialist knowledge of the underlying physical principles upon which CFD packages are based. Generally users...

In the past 50 years, Computational Wind Engineering (CWE) has undergone a successful transition from an emerging field into an increasingly established field in wind engineering research, practice and education. This paper provides a perspective on the past, present and future of CWE. It addresses three key illustrations of the success of CWE: (1) the establishment of CWE as an individual rese...
