A CFD Model for the Pecvd of Silicon Nitride
Proceedings. IEEE/SEMI Advanced Semiconductor Manufacturing Conference and Workshop, 1994This work describes the methodology used to develop a computational fluid dynamic (CFD) model for the plasma-enhanced chemical vapor deposition (PECVD) of silicon nitride (SiN/sub x/) for an N/sub 2/SiH/sub 4/-NH/sub 3/ process. The model has been developed for the Applied Materials Precision 5000 single-wafer reactor, and has the reaction chamber ...

CFD modeling of bubble-induced turbulence
International Journal of Multiphase Flow, 2013Abstract Modeling of bubble-induced turbulence in dispersed gas–liquid multiphase flow is an important but still unresolved issue. Aside from its intrinsic interest, turbulence in this type of flow has a strong impact on other important processes like turbulent dispersion of the bubbles and bubble-coalescence and -breakup and thus is a central part ...

The prediction of the supersonic ejector dynamics implies the accurate description of all the complex flow features discussed in Chap. 2. Unfortunately, the theoretical modeling approach necessitates a number of simplifying assumptions and empirical constants that introduce significant uncertainty and reduce the capability of capturing a number of ...

A compact wall model for CFD simulations
2017 16th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm), 2017It is often necessary to model both internal and external walls in CFD simulations, especially at the room level. Actual walls are generally composed of multiple (thin) layers and may be exposed to solar irradiance. Modeling the wall construction explicitly can be tedious (because of complexities at wall intersections) and also problematic, as the ...

Abstract Agitated gas-liquid reactors are widely used in the biochemical industry. In aerobic fermenters the dissolution of oxygen to the fermentation broth is impportant for the efficient operation of the reactor. In order to make accurate designs for bioreactors the local reaction and mass transfer conditions need to be modelled in detail.

Simulation of VCEs by CFD modelling: an analysis of sensitivity
Journal of Loss Prevention in the Process Industries, 1998The AutoReaGas code developed by TNO and Century Dynamics Ltd has been utilized to simulate the occurrence of a Vapour Cloud Explosion in a large fuel storage area. The sensitivity of the results to the main input variables has been investigated, together with the effect of fuel amount and fuel concentration inside the cloud.

ADVANTAGES AND CONSTRAINTS OF CFD GREENHOUSE MODELLING
Acta Horticulturae, 2011For the first attempts to model the greenhouse climate using Computer Fluid Dynamics (CFD), this approach has gained ground and the number of studies in this field is continuously growing in an increasing variety of application domains. As illustrated by the acceleration of the number of publications and the abundance of review papers on this topic ...

CFD Modelling of an Electrodialysis Cell
ECS Meeting Abstracts, 2018Electrodialysis (ED) cells are based on the selective transport of ions through membranes which ideally exclude the co-ions, so that when a potential difference is applied to the cell all ions are transported in solution but only the counter ions can cross the membrane.
