Detailed velocity profiles in close-coupled elbows—Measurements and computational fluid dynamics predictions (RP-1682)

Detailed Computational and Experimental Fluid Dynamics of Fluid Beds

To describe the hydrodynamic phenomena prevailing in large industrial scale fluidised beds continuum models are required. The flow in these systems depends strongly on particle-particle interaction and gas-particle interaction. For this reason proper closure relations for these two interactions are vital for reliable predictions on the basis of continuum models. Gas-particle interaction can be ...

Experimental study and application of computational fluid dynamics on the prediction of air velocity and temperature in a ventilated chamber

The shape of the air flow in the interior is heavily influenced by the air distribution system and the way air enters and exits. By numerically simulating flow by computational fluid dynamics, one can determine the flow pattern and temperature distribution and, with the help of the results, provide an optimal design of the air conditioning system. In this study, a chamber was first constructed ...

FEniCS-HPC: Coupled Multiphysics in Computational Fluid Dynamics

Reactor Simulation with Coupled Monte Carlo and Computational Fluid Dynamics

This paper demonstrates the applicability of Monte Carlo analysis to perform nuclear reactor core simulations with thermofluid feedback from a computational fluid dynamics code. An interface program, McSTAR, was written to couple MCNP5 to the commercial computational fluid dynamics code STAR-CD. McStar is a Perl script which alternately executes MCNP5, STAR-CD and cross section update routines ...

Computational fluid dynamics simulations guided by Fourier velocity encoded MRI

Introduction: Fourier velocity encoding (FVE) is a promising MRI method for assessment of cardiovascular blood flow. FVE provides considerably higher signal-to-noise ratio (SNR) than phase contrast (PC) imaging, and is robust to partial-volume effects. On the other hand, FVE does not directly provide velocity maps. These maps are useful for calculating the blood flow through a vessel, or for gu...
