Modeling Alpha-Galactosides Behavior during Cowpea Soaking-Cooking for Nutritional Optimization

A. Briffaz [1], F. Coffigniez [1], C. Mestres [1], P. Bohuon [2],
[1] CIRAD, France
[2] Montpellier SupAgro, France

Cowpea seed is a pulse which is very rich in vital micronutrients but also in anti-nutritional factors such as α-galactosides (verbascose, stachyose and raffinose) that can cause digestive disorders after consumption. The objective of this work was to identify the transport and ... Read More

Simulation of an Ethane Steam Cracking Reactor for Ethane-Propane Mixtures

R. Martinez [1], J. A. Galán [2], Y. Amaya [1], H. S. Arenas [1]
[1] Universidad Industrial de Santander, Bucaramanga, Santander, Colombia
[2] Empresa Colombiana de Petróleos, Barrancabermeja, Santander, Colombia

This study allows to establish the possibility to carry out the pyrolysis of mixtures of ethane-propane in an existing steam-cracking reactor (SCR) originally designed for ethane pyrolysis. The final goal of this study was to minimize new investments, e.g. a purchase of new equipment, ... Read More

Synthetic nanofluidic architectures that mimic the gating functions of biological ion ... Read More

Simulation of Thin Film All-Solid-State Lithium Ion Batteries

M. Fukukawa [1], L. Tong [1],
[1] Keisoku Engineering System Co., Ltd., Chiyoda-ku, Tokyo, Japan

There is great interest in developing all-solid-state lithium-ion batteries. They are ideal micro-power sources for many applications in portable electronic devices, electric vehicles and biomedical engineering. The batteries are possessed of high energy and power densities, good ... Read More

Modeling a Concentrated Solar Thermal Collector for Methane Dry Reforming

S. Verma [1], N. Hotz [1],
[1] Duke University, Durham, NC, USA

Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... Read More

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
