Analysis Tools for CFD Multigrid Solvers
Analysis tools are needed to guide the development and evaluate the performance of multigrid solvers for the fluid flow equations. Classical analysis tools, such as local mode analysis, often fail to accurately predict performance. Two-grid analysis tools, herein referred to as Idealized Coarse Grid and Idealized Relaxation iterations, have been developed and evaluated within a pilot multigrid ...
متن کاملCFD Hydrodynamics Analysis of Syngas Flow in Slurry Bubble Column
In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...

متن کاملCombined CFD/MRI Analysis of Left Ventricular Flow
The relationship between the morphology and blood flow of the Left Ventricle (LV) during myocardial remodelling is complex and not yet fully understood. Cardiovascular MR (CMR) velocity imaging is a versatile tool for the observation of general flow patterns in-vivo. More detailed understanding of the coupled relationship between blood flow patterns and myocardial wall motion can be further enh...
متن کاملCFD Analysis of Single and Multiphase Flow Characteristics in Elbow
Computational fluid dynamics (CFD) analysis of singlephase and two-phase flow was performed in a 90 degree horizontal to vertical elbow with 12.7 mm inside diameter. Characteristic flow behavior was investigated at six different upstream and downstream locations of the elbow. To evaluate the effects of different phases, three different air velocities and three different water velocities were us...
