Implementation of a Viscoelastic Model to Generate a Shear Stress Test Using the DEVSS/SUPG Method

A. Amos Benchimol [1], C. Dubois [1], F. Bertrand [1], D. Vidal [1],
[1] Ecole Polytechnique of Montréal, Montréal, QC, Canada

Viscoelastic flow of polymer based energetic materials exiting an extrusion die is a particularly challenging phenomenon to describe by modelling and simulation due to non-Newtonian effects in the die and significant swelling at the exit. This project aims to develop a simulation model ... Per saperne di più

[2] Department of Chemical and Biomedical Engineering, Cleveland State University, Cleveland, OH, USA

Optimization of mixing in microfluidic devices is a popular application of computational fluid dynamics software packages, such as COMSOL Multiphysics, with an increasing number of studies being published on the topic. On one hand, the laminar nature of the flow and lack of turbulence in ... Per saperne di più

Flotation Height in 'Air Hockey' Spatial Atomic Layer Deposition

J. Grasso [1], B. Willis [1],
[1] Department of Chemical and Biomolecular Engineering, University of Connecticut, Storrs, CT, USA

Atomic layer deposition(ALD) is one proven method to deposit ultra-thin films. ALD is advantageous for its atomic-level thickness control and conformity; leading to high quality films. Slow deposition rates for conventional ALD contribute to the impracticality of utilization of this ... Per saperne di più

Evaluating Clean Bench Designs Using CFD and Particle Tracing

A. Johnson [1] , M. Wright [1]
[1] Honeywell FM&T, Kansas City, MO, USA

At the Kansas City National Security Campus (KCNSC), simulation analysts are often called upon to evaluate designs and manufacturing processes performed in the plant. Precision mechanisms need to be assembled on clean benches that provide laminar airflow to prevent dust contamination. ... Per saperne di più

Design and Simulation of 3D Printed Check Valves Using Fluid-Structure Interaction

A. M. Melvin [1], T. J. Roussel [1],
[1] Department of Bioengineering, J.B. Speed School of Engineering, University of Louisville, Louisville, KY, USA

Passive, one-way valves, also known as check valves, while common at the macro scale, are an essential microfluidic feature that facilitate flow rectification. These structures are also commonly used in reciprocating micropump configurations to control flow. Their operation can be ... Per saperne di più

COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes

J. Bush [1],
[1] Old Dominion University, Norfolk, VA, USA

The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... Per saperne di più

Computational Fluid Dynamic Study of Fixed Bed Reactor of Hydrotreating of Vegetable Oil

N. Casillas [1], L. Olivo [1],
[1] Instituto Politécnico Nacional, Ciudad de México, México

Hydrodynamics of fixed bed reactors involve complex interactions of gas and liquid phases with packed solids. Such complex interactions manifest in different flow regimes occurring in trickle-bed reactors. A comprehensive CFD model was developed to predict measured hydrodynamic ... Per saperne di più

Catalytic Oxidative Dehydrogenation of Propane to Propylene

E. B. Ledesma [1],
[1] University of St. Thomas, Houston, TX, USA

Propylene is the second most important olefin and the second largest volume industrial chemical produced globally. In 2015, the global demand for propylene was about 94 million metric tons. The largest use for propylene is the production of polypropylene, consuming 67% of propylene ... Per saperne di più
