A leading computational fluid dynamics (CFD) software FLUENT is ported to the NCSA IA-32 Linux cluster with Myrinet interconnect. Scripts are written to integrate FLUENT with the open-source PBS scheduling system. Scalable performance of FLUENT is benchmarked with two engineering problems from Caterpillar Inc. and Fluent, Inc. A maximum of 64 processors are used to accommodate up to 10 million ...

The objective of this paper is to provide an investigation, using large eddy simulations, into the dispersion of aircraft jets in co-flowing take-off conditions. Before carrying out such study, simple turbulent plane free and wall jet simulations are carried out to validate the computational models and to assess the impact of the presence of the solid boundary on the flow and dispersion propert...

Fluent, as one of the commercial CFD packages, the author discussed its application in greenhouse ventilation research. In the paper, the under problems would be expounded: in fluent what models will be used in greenhouse studying, and the details during in these models used, and the comparing of the same style models. The steps to solve the greenhouse problem also was expatiate in this paper, ...

The Ogee Spillway is one of the most crucial flood control structures, and it developed at same time as dams. Spillway's downstream portions experience scouring due to flow, a problem that persists in reality. This paper aims investigate hydraulic performance stepped block dissipater using three-dimensional simulation model. dissipated was given new distribution may be one, two, or three rows t...

In the present work, the pyrolysis of acetylene was studied under steel vacuum carburizing conditions in a tubular flow reactor. The pyrolysis temperature ranged from 650 degrees C to 1050 degrees C. The partial pressure of acetylene in the feed mixture was 10 and 20 mbar, respectively, while the rest of the mixture consisted of nitrogen. The total pressure of the mixture was 1.6 bar. A kinetic...

Labyrinth weirs have not a straight crest in the perpendicular direction to the flow. The plan view of the weir consists of multiple and broken linear crests that cause the increase of its effective length. The advantages of this type of weirs are higher discharge capacity, easy aeration as well as low fluctuations of water surface at the weir upstream. This paper deals with the simulation of t...
