Blood Flow Patterns in a Patient Specific Right Coronary Artery with Multiple Stenoses

B. Liu[1]
[1]Department of Mathematics, Monmouth University, West Long Branch, NJ, USA

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the ... Mehr lesen

Simulation of a New PZT Energy Harvester with a Lower Resonance Frequency Using COMSOL Multiphysics®

H. Elbahr[1], T. Ali[1,2], A. Badawi[1], S. Sedky[1]
[1]Zewail City of Science and Technology - Cairo, Cairo, Egypt
[2]Cairo University, Cairo, Egypt

Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low ... Mehr lesen

Evaluation of Instability of a Low-salinity Density-dependent Flow in a Porous Medium

Y. T. Habtemichael[1], R. T. Kiflemariam[2], H. R. Fuentes[1]
[1]Department of Civil & Environmental Engineering, Florida International University, Miami, FL, USA
[2]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

Seawater intrusion into coastal aquifers is usually modeled by using transport models that include account for the effect of variable-density on flow. Variable-density models can be validated with the Henry and Elder benchmark problems. However, when mixed convective flow is simulated ... Mehr lesen

3D COMSOL Multiphysics® Model of a Plate Heat Exchanger to Support a Laboratory Teaching Environment

N. Medeiros[1], W. Clark[1]
[1]Worcester Polytechnic Institute, Worcester, MA, USA

Chemical engineering students and practitioners need an understanding of fluid flow and heat transfer inside heat exchangers. Because the flow within plate heat exchangers is difficult to visualize, we developed COMSOL Multiphysics® simulations of plate heat exchangers for students to ... Mehr lesen

High Frequency Resonators Using Exotic Nanomaterials

B. Panchapakesan[1], M. Loeian[1]
[1]Department of Mechanical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

Human made mechanical resonators have been around for a thousand years. Early applications included musical instruments and chronographs operating in millihertz to kilohertz frequencies while more recent interest has turned ultra-high frequency resonators and oscillators suitable for ...

Estimativa do Fluxo de Calor em uma Ferramenta de Corte Durante um Processo de Usinagem com o Uso do Software COMSOL Multiphysics® e de Técnicas de Problemas Inversos

R. F. Brito[1], S. R. de Carvalho[2], S. M. M. de L. e Silva[1]
[1]Federal University of Itajubá - UNIFEI, Itabira, Minas Gerais, Brasil
[2]Federal University of Uberlândia - UFU, Uberlândia, Minas Gerais, Brasil

This work proposes the use of inverse problem techniques in connection with COMSOL to estimate the heat flux and the temperature field on a turning cutting tool in transient regime. The main purpose of the present work is to present the improvements performed in relation to the authors’ ... Mehr lesen

Residence Time Distribution for Tubular Reactors

L. R. de Souza Jr.[1], L. Lorenz[1]
[1]Universidade Federal do Paraná, Curitiba, Paraná, Brazil

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal ... Mehr lesen

FEM Analysis of Flamelet Wrinkling in a Diffusion Flame

Y. Li[1], T.C. Lieuwen[2], J. Zhou[1], H. Cao[1]
[1]Zhengzhou University, Zhengzhou City, Henan Province, China
[2]Georgia Institute of Technology, Atlanta, GA

One can hardly get the exact analytic solution of a full time-dependent convection-diffusion equation, for describing the dynamics of a non-premixed flamelet. The analytic solution of the linearized form with such a model was studied by MATLAB®. And also, a numerical computation was made ... Mehr lesen

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 ... Mehr lesen
