Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... Read More

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 ... Read More

Flow Modeling in Long Surface Patterned Micromixers Using Division in Multiple Geometrical Subunits

[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 ... Read More

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 ... Read More

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. ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

3D Unsteady CFD Simulation of Seasonal Solar Thermochemical Heat Storage System for Buildings

W. Yaïci [1], E. Entchev [1],
[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... Read More
