Modelling of a Single Cardiomyocyte Interaction with a Microcantilever Using COMSOL Multiphysics®

I. Banerjee[1]
[1]Tampere University of Technology, Tampere, Finland

: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are ... En savoir plus

Numerical Investigation of Swirl Flow in Curved Tube with Various Curvature Ratio

A. Kadyirov[1]
[1]Research Center for Power Engineering Problems of the Russian Academy of Sciences, Kazan, Russia

The influences of curvature effects and swirl intensities for Non-Newtonian viscous fluid flow in a curved tube have been numerically investigated by using COMSOL Multiphysics®. The twisted tape, which are located directly in front of the curved part, are used as swirl flow generators. ... En savoir plus

Numerical Modeling and Performance Optimization Study of a Diaphragm Pump for Medical Application

I. Lupelli[1], P. Gaudio[1], A. Malizia[1], R. Quaranta[1]
[1]Department of Industrial Engineering, University of Rome “Tor Vergata”, Roma, Italy

In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation ... En savoir plus

Rheological Behaviour of Single–Phase Non-Newtonian Polymer Solution in Complex Pore Geometry: A Simulation Approach

P. Idahosa[1], G. Oluyemi[2], R. Prabhu[2], B. Oyeneyin[2]
[1]IDEAS Research Institute/School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.
[2]School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.

One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete ... En savoir plus

Numerical Study of a DC Electromagnetic Liquid Metal Pump: Limits of the Model

N. Kandev[1]
[1]Institut de recherche d'Hydro-Québec, Shawinigan, QC, Canada

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation ... En savoir plus

Direct Numerical Simulation of Time Evolution of Vortex Ring

M. Hashiguchi [1],
[1] Keisoku Engineering System Co., Ltd., Chiyoda-ku, Tokyo, Japan

Vortex ring can be useful to generate thrust force for e.g., jellyfish, but its mechanism has not been clarified. In this field, it seems that numerical simulation has an important role of understanding the propulsion mechanism of creature. A vortex ring in a tube, refered to confined ... En savoir plus

Efficiency of a Vertical Axis Wind Turbine (VAWT) with Airfoil Pitch Control

J. Ma [1], C. Koutsougeras [2], H. Luo [2],
[1] Sam Houston State University, Huntsville, TX, USA
[2] Southeastern Louisiana University, Hammond, LA, USA

In this work, the CFD Module of COMSOL Multiphysics® software is used to study the efficiency of a Vertical Axis Wind Turbine (VAWT) with independently pivoting airfoils so that wind attack angles of these airfoils are adjustable. The work demonstrates how the efficiency of the VAWT is ... En savoir plus
