The results from an experimental and numerical study of a known mouse cage (static microisolator type) placed in a wind tunnel are presented. The study involved the collection of experimental airflow data and the use of these data in the validation of the computational fluid dynamics (CFD) cage model. This validation was important as it then allowed the CFD cage model to be used to represent ca...

A 1D3D–CFD coupled spray model is proposed in this work for the simulation of Diesel sprays under non-evaporative conditions and constant injection velocity in time. The basic idea of the model is to reduce the poor estimations of the gas velocity and droplets/gas relative velocity obtained with the standard 3D–CFD Eulerian–Lagrangian spray model, when coarse meshes are used. The coupling has b...

Computational fluid dynamics (CFD) is a simulation tool, which uses powerful computer and applied mathematics to model fluid flow situations for the prediction of heat, mass and momentum transfer and optimal design in industrial processes. It is only in recent years that CFD has been applied in the food processing industry. This paper reviews the application of CFD in food processing industries...

This paper presents the CFD modeling methodology and validation for steady-state, normal operation in a PWR fuel assembly. This work is part of a program that is developing a CFD methodology for modeling and predicting single-phase and two-phase flow conditions downstream of structural grids that have mixing devices. The purpose of the mixing devices (mixing vanes in this case) is to increase t...

Previous studies indicated that the coupling of multizone and CFD (Computational Fluid Dynamics) models can provide a good compromise between the accuracy and required computation time. The results show that the coupled model predicts contaminant distribution more accurately than multizone model alone for the zones close to the contaminant source location. For all other zones, the multizone mod...

This work focuses on the development of a multiscale computational fluid dynamics (CFD) simulation framework with application to plasma-enhanced chemical vapor deposition of thin film solar cells. A macroscopic, CFD model is proposed which is capable of accurately reproducing plasma chemistry and transport phenomena within a 2D axisymmetric reactor geometry. Additionally, the complex interactio...

The objective of this research is to compare the use of empirical correlation with Computational Fluid Dynamics (CFD) simulation in determining the pressure gradient in two-phase flow pipelines at the same inlet condition. In this work, the empirical model of Beggs and Brill model had been used whereas the turbulent model applied in the CFD simulation was the Renormalization Group (RNG) k-ε mod...

This paper describes and analyzes a series of nearly CFD test cases performed as a contribu tion to the second Drag Prediction Workshop held in association with the AIAA in June Two con gurations are included DLR F wing body and wing body nacelle pylon The ability of CFD to pre dict the drag lift and pitching moment from exper iment including the delta arising from the ad dition of the nacelle ...

Understanding and modelling of main annulus gas ingestion through turbine rim seals is considered and advanced in this paper. Unsteady 3-dimensional computational fluid dynamics (CFD) calculations and results from a more elementary model are presented and compared with experimental data previously published by Hills et al (1997). The most complete CFD model presented includes both stator and ro...
