Development of a User Interface for Design of SO2 Oxidation Fixed-Bed Reactors

A. Nagaraj [1], P. L. Mills [1],
[1] Texas A&M University - Kingsville, Kingsville, TX, USA

H2SO4 is a very important chemical commodity, and indeed, a nation’s H2SO4 production has been a reasonably good indicator of its industrial strength for the last century or so1,2. Nearly 350 MM tons of H2SO4 was produced in 20143.The demand for H2SO4 in United States exceeds the supply ... Per saperne di più

Novel Approach for Teaching Microchemical Systems Analysis to Chemical Engineering Students Using Interactive Graphical User Interfaces (GUIs)

A. Nagaraj [1], P. L. Mills [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

Chemicals are an integrated part of our daily life. While chemicals are significant contributor to a nation’s economy, sound management of chemical production is essential for environmentally friendly operation without maximizing operational costs. Next generation technologies must be ... Per saperne di più

Computer Simulation of Microwave Heating of Initially Frozen Sandwiches Using COMSOL Multiphysics® Application Builder

D. Fu [1], L. Wang [2], J. Liao [1], S. Dus [1], K. Bearson [1],
[1] Tyson Foods, Downers Grove, IL, USA
[2] Simulprocess, Summerfield, NC, USA

Customers typically prepare sandwiches using a microwave oven to heat a frozen sandwich. This causes huge temperature variations and quality issues due to multicomponent with different dielectric and physical properties and with phase changes at different freezing points in the heating ...

Elucidating the Mechanism Governing Particle Alignment and Movement by DEP

G. Zhang [1], Y. Zhao [1], J. Brcka [2], J. Faguet [2],
[1] Clemson University, Clemson, SC, USA
[2] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA

We have simulated alignment and movement of multiple particles under Dielectrophoresis (DEP) using the Particle Tracing Module in COMSOL Multiphysics® software with particle-particle interaction taken into consideration. We are able to do efficient modeling for both 2D and 3D cases. With ... Per saperne di più

Simulation of a Buckled Cantilever Plate with Thermal Bimorph Actuators

[2] Physical Sciences and Engineering Division, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[3] University of British Columbia, Vancouver, BC, Canada

INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... Per saperne di più

Assessment of Diffuse Optical Tomography Image Reconstruction Methods Using a Photon Transport Model

M. M. Althobaiti [1], H. S. Salehi [2], Q. Zhu [2],
[1] Department of Biomedical Engineering, University of Connecticut, Storrs, CT, USA
[2] Department of Electrical and Computer Engineering, University of Connecticut, Storrs, CT, USA

Imaging of tissue with near-infrared diffuse optical tomography is emerging as a practical method to map hemoglobin concentrations within tissue for breast cancer detection and diagnosis. The accurate recovery of images by using numerical modeling requires an effective image ... Per saperne di più

Control the Poly-Dispersed Droplet Breakup Mode in a Droplet-based Microfluidic Device by External Electric Field

Y. Li [1], K. Nandakumar [1], M. Jain [1],
[1] Cain Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA, USA

Droplet–based microfluidics has received special research attentions in last two decades due to its superior control over fluid flow as well as other unique advantages[1]. By introducing two immiscible fluids into microfluidic systems, the reagent fluid is encapsulated inside discrete ... Per saperne di più

FEM Convergence for PDEs with Point Sources in 2-D and 3-D

M. Gobbert [1], K. M. Kalayeh [2], J. S. Graf [1],
[1] Department of Mathematics and Statistics, University of Maryland - Baltimore County, Baltimore, MD, USA
[2] Department of Mechanical Engineering, University of Maryland - Baltimore County, Baltimore, MD, USA

Numerical theory provides the basis for quantification of the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in COMSOL Multiphysics® software to perform computational studies for ... Per saperne di più
