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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

Modeling of Asphaltenes and Oil Shale Pyrolysis

J. P. Mmbaga[1], F. Munoz[2], S. Dhir[1], R. Gupta[1], R. E. Hayes[1], M. Toledo[2]
[1]University of Alberta, Edmonton, AB, Canada
[2]Departamento de Ingenieria Mecanica, Universidad Tecnica Federico Santa Maria, Valparaiso, Chile

Pyrolysis is a key step in the conversion of carbonaceous materials into useful products. In this study, we investigate the pyrolysis of asphaltene and oil shale, both experimentally and numerically. COMSOL Multiphysics® software is used to model the combined effects of fluid flow in ... Mehr lesen

Multiphysics: Fluid Mixing and Brine Pool Formation for Economic Geology Applications

C. Schardt[1]
[1]University of Minnesota-Duluth, Duluth, MN, USA

Significant submarine mineral deposits form when hot, metal-laden, saline fluids emerge onto the seafloor and mix with ambient seawater. Resulting density changes of fluid mixtures can trigger fluid buoyancy reversals, brine pool formation, and metal accumulation (Figure 1). While some ... Mehr lesen

Modeling Integrated Thermoelectric Generator-Photovoltaic Thermal (TEG-PVT) System

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

2D steady state heat conduction-electric current model was created in COMSOL Multiphysics® software to study the performance of thermoelectric generator-photovoltaic-thermal (TEG-PVT) system. Four different cases were studied in the paper. In case 1, PV cells without concentrator was ... Mehr lesen

A Computational Study on Thermal Conductivity Measurements of High Temperature Liquid Materials

X. Ye[1], R. W. Hyers[1]
[1]Department of Mechanical & Industrial Engineering, University of Massachusetts - Amherst, Amherst, MA, USA

Accurate thermo-physical properties of materials are valuable for both scientific research and industrial applications. For high temperature liquid materials, two issues exclude traditional methods: elevated reactivity of test material and experimental apparatus, uncontrolled heat ... Mehr lesen

Microvascular Dysfunction in PAD Patients

K. Cluff[1], H. Mehraein[1], B. Jayakumar[2]
[1]Department of Bioengineering, Wichita State University, Wichita, KS, USA
[2]Department of Industrial & Manufacturing Engineering, Wichita State University, Wichita, KS, USA

Background: Peripheral arterial disease (PAD) is characterized by atherosclerotic blockages of the arteries supplying the lower extremities, which cause a progressive accumulation of ischemic injury to the skeletal muscles of the lower limbs. Despite revascularization treatment ... Mehr lesen

Calibration of a Geothermal Energy Pile Model

R. Caulk[1], J. McCartney[2], E. Ghazanfari[1]
[1]University of Vermont, Burlington, VT, USA
[2]University of Colorado, Boulder, CO, USA

In this study, a model of in-situ geothermal energy piles was constructed using COMSOL Multiphysics® software. Geothermal energy piles serve two purposes, first to transfer building load into the subsurface, but also to extract thermal heat from surrounding soils. This is achieved using ... Mehr lesen

Drag Fluctuations of a Fully Deployed Flow Actuator Embedded Inside Turbulent Boundary Layer Flow

Dr. A. Elzawawy[1]
[1]Engineering & Technology Department, Vaughn College of Aeronautics & Technology, Flushing, NY, USA

Introduction: In this work, a CFD model of 2D flow around a fully deployed flow actuator was developed using COMSOL Multiphysics® software and the CFD Module. The results of COMSOL modeling is also compared with the experimental data of the same dimensions actuator. The 100mmX2mm ... Mehr lesen
