Mechanistic Understanding of Food Microbiological Safety: Multiphase Transport Through a Leaf Stomate During Vacuum Cooling

M. Ranjbaran [1], A. K. Datta [1],
[1] Cornell University, Ithaca, NY, USA

Vacuum cooling is a common unit operation in the leafy greens industry and is considered as a very efficient approach to extend the shelf-life of fresh produce. However, during this popular process, bacteria can internalize into the produce. This emphasizes the need for better ... Read More

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

J. Clark [1], T. A. Butt [1], G. Mahajan [2], C. R. Kothapalli [2], M. Kaufman [1], P. S. Fodor [1]
[1] Department of Physics, Cleveland State University, Cleveland, OH, USA
[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

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

Simulation of an Oxygen Delignification Reactor in the Kraft Pulp Production Process

D. do Mato Lara [1], J. da Luz Maeiski [1], I. Neitzel [1]
[1] Faculdade de Telêmaco Borba, Telêmaco Borba, PR, Brazil

Oxygen delignification is a technology established worldwide and a common operation in pulp mills that use Kraft cooking. The reasons for using this technology are the reduction of organochlorine compounds in the effluents, and economy of chemicals in the bleaching stage. The objective ... Read More

Simulation of Adsorption Mechanisms of Methane and Carbon Dioxide in Shale Matrix

J. G. Moreira [1], A. L. Manriquez [1],
[1] Texas A&M University - Kingsville, Kingsville, TX, USA

The aim of this research is to contribute with the development of Carbon Capture and Storage techniques by studying carbon dioxide (CO2) adsorption mechanisms in shale reservoirs. Gas desorption is considered a major gas production mechanism and has a relevant role in shale gas ... Read More

Mathematical Modeling of Drug Transport in Brain Tumors

Y. Guo [1], M. O. Bernabeu [2], C. D. Arvanitis [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA
[2] University of Edinburgh, Edinburgh, United Kingdom

Blood-brain and blood-tumor barriers (BBB and BTB) constitute a major obstacle to the transport of therapeutics in brain tumors. Focused ultrasound (FUS), when combined with circulating microbubbles, provides a noninvasive method to locally and transiently disrupt the BBB/BTB. ... Read More

Diffusive Transport in a Deep Geological Repository for Used Nuclear Fuel

M. Krol [1], S. Briggs [2],
[1] York University, Toronto, ON, Canada
[2] Nuclear Waste Management Organization, Toronto, ON, Canada

The Nuclear Waste Management Organization (NWMO) is developing a deep geological repository as part of Adaptive Phased Management (APM), Canada’s plan for the long-term management of used nuclear fuel. The repository is a multiple barrier system to protect people and the environment. To ... Read More

A Microfluidic Platform for Electrochemical Concentration and Detection

C. F. Ivory [1], D. E. Molina [1],
[1] Washington State University, Pullman, WA, USA

A poly(methyl methacrylate) (PMMA) microfluidic platform with a hot-embossed microchannel, 150 mm wide and 20 mm deep, was developed for multiple purpose detection using electrochemical methods. This device is able to accommodate a three-electrode system encased in 1/16" diameter PEEK ... Read More

Effects of Geometry and Operating Conditions on Membrane Reactor for Water Gas Shift Reaction

D. Shin [1], T. Kim [1], J. Lee [1]
[1] Altsoft Inc., Seoul, South Korea

Recently, hydrogen is widely used as environmental energy and high energy content. The hydrogen is mainly produced by water gas shift reaction(WGSR) from coal to hydrogen process in Integrated Gasification Combined Cycle(IGCC) plant. WGSR, well known for hydrogen production, is a ... Read More
