Estimation of Critical Parameters of Drop-Drop Electrocoalescence Using a Multiple-Drop System

S. S. Kulkarni[1], V. A. Juvekar[1], A. Chheda[2]
[1]Indian Institute of Technology Bombay, Mumbai, Maharashtra, India
[2]Institute of Chemical Technology, Mumbai, Maharashtra, India

Electrocoalescence is the phenomenon of coalescence of droplets suspended in an insulating liquid or in a gas under the action of an electric field. Electrocoalescence is considered a promising tool in many petrochemical industries for desalting crude oils. However, this technique ... Read More

Boundary Value Effects on Migration Patterns in Hydraulically Fractured Shale Formations

T. Aseeperi[1]
[1]Department of Chemical Engineering, University of Arkansas, Fayetteville, AR, USA

During the hydraulic fracturing process, there can be possible re-activation of closed/sealed faults and natural fractures in the formation, which may lead to changes in the boundary conditions of the reservoir. While study models of shale gas formations have utilized the concept of a ... Read More

Numerical Simulation of Carbon Steel Corrosion Exposed to Flowing NaCl Solutions Through an Annular Duct

A. Soliz[1], K. Mayrhofer[1], L. Caceres[2]
[1]Department of Interface Chemistry & Surface Engineering, Max-Planck-Institut für Eisenforschung, Düsseldorf, Germany
[2]Department of Chemical Engineering, University of Antofagasta, Antofagasta, Chile

A three-dimensional mathematical model under stationary conditions have been established to understand the corrosion of carbon steel cylindrical samples immersed in flowing NaCl solution through an annular duct. The migration, diffusion and convection mass transfer mechanisms were solved ... Read More

Modeling of a Multilayered Propellant Extrusion in Concentric Cylinders

S. Durand[1,3], C. Dubois[1], P. Lafleur[1], V. Panchal[2], D. Park[2], D. Lepage[3], P. Paradis[3]
[1]École Polytechnique de Montréal, Montréal, QC, Canada
[2]US Army ARDEC, Picatinny Arsenal, NJ, USA
[3]General Dynamics OTS Canada Valleyfield, Valleyfield, QC, Canada

A novel propellant technology requires extruding two formulations with differential burning rates together as a multilayered propellant. This propellant is processed into a concentric cylinder configuration, in the form of slow-fast-slow with single perforation. The material uses ... Read More

Comparison of Different Passive Oil-Water Mixing Schemes in a Flow Loop

A. Chaudhuri[1]
[1]Materials Synthesis & Integrated Devices, Los Alamos National Laboratory, Los Alamos, NM, USA

Oil and water are immiscible fluids and they tend to separate very easily when introduced into a flow stream from two different sources in a flow loop. This model studies the development of mixture volume fraction in an oil-water-flow loop with 3 different passive mixing schemes: (i) ... Read More

Study of the Process, Design, and Operating Parameters Effect on the Efficiency of the Process Mill

A. K. Farouk[1]
[1]Department of Mathematics & Natural Science, University of Stavanger, Sandnes, Rogaland, Norway

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers ... Read More

Static and Dynamic Deformations of a Reed Valve Immersed in Hydraulic Fluid

A. Chaudhuri[1]
[1]Los Alamos National Lab, Los Alamos, NM, USA

Metal reed valves are used for flow rectification in electrohydraulic pumps driven by smart materials at high frequencies but it is difficult to predict their behavior when the surrounding fluid has considerable inertia and viscosity. Simulation of this phenomenon involves modeling the ... Read More

Enhanced Transient Modeling of Hybrid Photovoltaic Air (PVT) Module

R. Kiflemariam[1], M. Almaz[1], F. Zevallos[1], C. Lin[1]
[1]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air ... Read More

Effect of Substrate Contact Angle on Ink Transfer in Flexographic Printing

F. E. Hizir[1], D. E. Hardt[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Flexography is a roll-based mass printing process used in manufacture of printed products such as sensors, self-cleaning surfaces, and flexible electronics. Flexography involves inking of a stamp wrapped around a roller, and the transfer of ink on the stamp surface to a printing ... Read More

Modeling of Asphaltenes and Oil Shale Pyrolysis
