Process Intensification Efforts towards Efficient, Modular, Solar-Thermochemical Production of Liquid Fuels

L. Freiberg [1], M. Coblyn [1], G. Jovanovic [1], N. AuYeung [1],
[1] Oregon State University, Corvallis, OR, USA

Concerning the reduction of fossil-energy use from industrial processes, power generation and transportation, concentrated solar power from dish reflectors is well suited for driving highly endothermic reactions that valorize CO2 and/or light hydrocarbons. In this study, a directly ... En savoir plus

Modeling the Electric Double Layer in Finite Electrolyte Solutions

J. C. Woehl [1],
[1] University of Wisconsin - Milwaukee, Milwaukee, WI, USA

While electric double layers play a crucial role in many biophysical processes involving charged molecular species (such as proteins and DNA), they are often a limiting factor in technological applications where charged conductors are brought in contact with electrolyte solutions. ...

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 ... En savoir plus

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 ... En savoir plus

Knowledge and Skills Acquisition via a “Parallel” Problem Solving Approach

J. R. Sanders [1], S. N. Jorgensen [1],
[1] Tennessee Technological University, Cookeville, TN, USA

To be competitive in today’s workforce, students in STEM undergraduate programs are expected to develop problem-solving skills.

[1] Department of Physics and Astronomy, Louisiana State University, Baton Rouge, LA, USA
[2] Department of Chemistry, Louisiana State University, Baton Rouge, LA, USA
[3] Department of Biological & Agricultural Engineering, Louisiana State University Agricultural Center, Baton Rouge, LA, USA

The IR CO2 laser powered chemical conversions in the gas phase are intriguing and the researchers’ attention was focused on this transformation a while ago. The method, known as Infrared Laser Powered Homogeneous Pyrolysis, or IR LPHP opened reaction pathways not reached by conventional ... En savoir plus

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 ... En savoir plus
