[3] Biomedical Engineering laboratory, University of Tlemcen, Algeria

This work is focused on Micropump optimization for drug delivery application. Diabetes is one of the widely pervaded diseases. Among the side effects of hyperglycemia is the weakness of the whole body, so the patient will be unable to inject manually the drug. Therefore, Micropumps are ... En savoir plus

Simulations of Blood Flow in the Left Atrial Appendage: Investigating Influence of Anatomical Shapes

Ondrej Fiser¹, David Vrba¹, Tomas Pokorny¹, Tomas Drizdal¹, Matous Brunat¹, Marek Novak¹, Jan Redr¹, Jan Vrba¹
¹Faculty of Biomedical Engineering, Czech Technical University in Prague

In this paper, we present a comprehensive study on the influence of anatomical shapes on the speed of blood flow in the left atrial appendage (LAA) using Computational Fluid Dynamics (CFD) Module in COMSOL Multiphysics®. The LAA itself can serve as a potential origin of blood clots, ... En savoir plus

Study of Rotation of Ellipsoidal Particles in Combined Simple Shear Flow and Magnetic Fields

C. Wang [1], J. Zhang [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study creates a 2D fluid-structure interaction (FSI) model to study the effect of magnetic field and particle aspect ratio on the period of rotation and symmetry of ellipsoidal paramagnetic particles. The results show that the magnetic field strength has a significant effect on the ... En savoir plus

A Heat Transfer Simulation for Heat Management in the Design of a New ReactorSTM

Elahe Motaee¹, Dr. Irene M.N. Groot¹
¹Leiden University

With the ReactorSTM the relationship between surface structure and catalyst activity under industrially relevant conditions can be investigated. It enables atomic-scale observations of model catalysts under conditions approaching those used by the chemical industry. It consists of a ... En savoir plus

Parametric Investigation of the Common Geometry Shapes for Added Mass Calculation

J. H. Lee [1], A. Koushesh [1],
[1] American University of Sharjah, United Arab Emirates

This work is aimed to demonstrate how variation of geometries' parameters would affect the fluid loading effect in water using COMSOL Multiphysics and compared with analytical data. When a structure is placed in water, the interaction between the water and the structure plays an ... En savoir plus

Release of the Model Substance Through the Polymer Membrane into the Biological Environment

Darya Zhurauliova ¹, Miloslav Pekar¹
¹Faculty of Chemistry, Brno University of Technology, Brno, CZ

Currently, there is a great interest in the study of gels, especially their transport or release properties. Hydrogels have countless definitions, but generally speaking, they are hydrophilic systems with a three-dimensional structure that tend to swell and hold large amounts of water ... En savoir plus

Development of Female and Male Thermoregulatory Models using COMSOL

Stefan Gutierrez¹, Juliette Jacques¹, Timothy Rioux¹, John Castellani ¹, Xiaojiang Xu¹
¹US Army Research Institute of Environmental Medicine, Natick, MA, US

Introduction Most current thermoregulation models represent the body in significantly simplified forms, e.g., cylinders or spheres. These simple geometries do not fully represent the complexity of bones, organs, etc. contained in the human body. Modern medical technologies allow for more ... En savoir plus

Chaining Dynamics of a Pair of Ellipsoidal Micro-Particles Under a Uniform Magnetic Field

J. Zhang[1], C. Wang[1]
[1]Missouri Univ of Sci and Tech, USA

Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... En savoir plus

Simulation of CMOS Compatible Sensor Structures for Dielectrophoretic Biomolecule Immobilization

H. Matbaechi Ettehad [1], S. Guha [1], C. Wenger [1],
[1] IHP, Frankfurt (Oder), Brandenburg, Germany

The aim of this paper is to optimize with COMSOL Multiphysics® simulation, the design geometry of a near field biosensor which could be used for dielectrophoretic (DEP) immobilization and simultaneous sensing of biomolecules of the order of nanometers to micrometers. COMSOL Multiphysics® ... En savoir plus
