Delamination of Sub-Crustal Lithosphere

P. Vincent[1], E. Humphreys[2]
[1]College of Earth, Ocean, & Atmospheric Sciences, Oregon State University, Corvallis, OR, USA
[2]Department of Geological Sciences, University of Oregon, Eugene, OR, USA

Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the ... En savoir plus

Design and Simulation of Valveless Piezoelectric Micropump

L. Nayana[1], P. Manohar[1], S. Babu[1]
[1]Department of Electrical Engineering, Visvesvaraya Technological University, Bangalore, Karnataka, India

In this paper some discrete parts of a valveless piezoelectric micropump for drug delivery system is designed and simulated. The core components of the micropump are actuator unit that converts the reciprocating movement of a diaphragm actuated by a piezoelectric actuator into a pumping ... En savoir plus

Comsol’s New Thermoviscous Interface and Computationally Efficient Alternative Formulations for FEM

W. R. Kampinga[1], and Y. H. Wijnant[2]
[1]Reden, Hengelo, Netherlands
[2]University of Twente, Enschede, Netherlands

Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. En savoir plus

Using a Level-Set Model to Estimate Dwell Time in a Vacuum Dewatering Process for Paper

K. Rezk[1]
[1]Department of Energy, Environmental and Building Technology, Karlstad University, Kronoparken, Sweden

Water removal during paper manufacturing is an intensive energy process. The dewatering process generally consists of four stages in which the first three stages, water is removed mechanically through vacuum pulses and pressing.The fourth stage involve thermal drying. The vacuum ... En savoir plus

Weak Form & LiveLink™ for MATLAB® Based Modified Uzawa Method For Solving Steady Navier-Stokes Equation

H. Sheng[1], S. Zhu[1]
[1]Shanghai Jiaotong University, Minhang, Shanghai, China

We demonstrate a simple example about how to design my own algorithm for Navier-Stokes equation by weak form PDE and LiveLink™ for MATLAB®. After the computation, we get the same solution as other FEM packages (FreeFEM++ & FeniCs) at each iterative step, and we can see the Navier ... En savoir plus

The Design of a Novel Roof Tile Shape Using CFD Analysis

M. Bottarelli [1], M. Bortoloni [1], G. Dino [1],
[1] University of Ferrara, Ferrara, Italy

In climates with high temperature and solar radiation, reducing the cooling consumption and increasing the standards of indoor comfort are topics of great importance. The roof plays a key role in controlling the indoor thermal comfort. In ventilated roofs, air flow within the ASV (Above ... En savoir plus

Mathematical Model of Blood Flow in Carotid Bifurcation

E. Muraca[1], V. Gramigna[1], and G. Fragomeni[1]
[1]Department of Experimental Medicine and Clinic, Magna Graecia University of Catanzaro, Catanzaro, Italy

The goal of this research is to provide the medical staff with a numerical system assessment of wall shear stress in carotid bifurcation. Through this model, it will be fundamental to investigate the stress state properties of the surface in contact between the plaque and the artery, and ... En savoir plus

CFD Modeling and Analysis of a Planar Anode Supported Intermediate Temperature Solid Oxide Fuel Cell

N. Lemcoff[1], M. Tweedie[2]
[1]Rensselaer Polytechnic Institute Hartford, Hartford, CT, USA
[2]Enthone, West Haven, CT, USA

A planar anode-supported intermediate temperature solid oxide fuel cell operating on syngas fuel at 750°C was analyzed in this study. The effects of varying syngas fuel inlet compositions on species and temperature distributions, water gas shift reaction rate, potential for carbon ... En savoir plus

Simulating Thermotherapeutic Response Induced by Thermal Padding for Treating Acute Injuries

J. Kantor[1], Y. Feng[1], C. Acosta[1], E. Massingill[1]
[1]University of Texas at San Antonio, San Antonio, TX, USA

Cryotherapy and thermotherapy are common methods of treatment for acute injuries ranging from ankle sprains to complex surgery. The idea behind such treatment is that a change in temperature will reduce pain and constrict fluctuations in blood flow at the targeted area. The purpose of ... En savoir plus
