The Numerical Simulation of Apokamp: A Novel Source of an Atmospheric-Pressure Plasma Jet

Vasily Kozhevnikov¹, Andrey Kozyrev¹, Natalia Semeniuk¹, Aleksandr Kokovin¹, Aleksei Sitnikov¹
¹Institute of High Current Electronics

In 2016 the group of experimentalists from the Institute of High Current Electronics (Tomsk, Russian Federation) have been discovered a novel phenomenon related to atmospheric plasma jets that was called an “apokamp” (originated from Greek words “off the bend”). This new plasma jet ... En savoir plus

Modeling the Thermal-Mechanical Behavior of Mid-Ocean Ridge Transform Faults

E. Roland[1], M. Behn[2], and G. Hirth[3]
[1]MIT/WHOI Joint Program, Woods Hole, MA, USA
[2]Woods Hole Oceanographic Institution, Woods Hole, MA, USA
[3]Brown University, Providence, RI, USA

To investigate the thermal-mechanical behavior of oceanic transform faults, we calculate 3-D steady-state incompressible mantle flow and heat transport using COMSOL Multiphysics. Our model incorporates a nonlinear viscous rheology with a visco-plastic approximation to simulate ... En savoir plus

Multiphysics Topology Optimization of Heat Transfer and Fluid Flow Systems

E. Dede[1]
[1]Toyota Research Institute of North America, Ann Arbor, Michigan, USA

This paper is focused on topology optimization of heat transfer and fluid flow systems for multiphysics objectives. Specifically, COMSOL Multiphysics software is coupled with a method of moving asymptotes optimizer in a custom COMSOL / MATLAB script. Various physical process including ... En savoir plus

Use of COMSOL In Aerodynamic Optimization of the UNLV Solar-Powered Unmanned Aerial Vehicle

L. Dube, W. McElroy, and D. Pepper

University of Nevada, Las Vegas, Nevada, USA

We discuss the use of COMSOL Multiphysics 3.4 in the aerodynamic optimization process of the UNLV solarpowered UAV. We also address the use of COMSOL’s Multiphysics ability and how it was used within the scope of the project. In particular we highlight the development of wingtip devices, ... En savoir plus

Mechanical and Thermal Effects of Focused Ultrasound on a Biological Tissue using COMSOL Multiphysics®, Three Different Approaches

N. El Sayed[1], A. Maurer[2], D. Enfrun[2], R. Rozsnyo[1]
[1]HES-SO Geneva, University of Applied Sciences and Arts Western Switzerland, Switzerland
[2]Kejako SA, Switzerland

Focused ultrasounds are used in many medical applications as a treatment: it is important to evaluate the induced effects of such a procedure to achieve a high accuracy while keeping the untargeted surrounding areas safe. In the present paper, COMSOL Multiphysics®, a simulation software ... En savoir plus

Statistics of Numerical Experiments with Multi-Fracture Systems

E. Holzbecher¹
¹German University of Technology, Halban, Oman

Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... En savoir plus

Microfluidic Separation System for Magnetic Beads

F. Wittbrach, A. Weddemann, A. Auge, and A. Hütten
Department of Physics, Bielefeld University, Germany

It is possible to control the motion of magnetic beads using a combination of hydrodynamic and electromagnetic forces. In this work, we investigate the possibility to manipulate the motion of beads with different magnetic moments in a special microfluidic structure so as to separate ... En savoir plus

A Model of Heat Transfer in Metal Foaming

Bruno Chinè [1], Valerio Mussi [2], Michele Monno [3], Andrea Rossi [2],
[1] School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica
[2] Macchine Utensili e Sistemi di Produzione, Piacenza, Italy
[3] Dipartimento di Meccanica, Politecnico di Milano, Milano, Italy

Metal foams are interesting materials with many potential applications. Foamed metals or alloys include gas voids in the material structure and therefore the density is introduced as a new variable, with the real possibility to modify ad hoc their physical properties. In the indirect ... En savoir plus

Newtonian and Non-Newtonian Blood Flow over a Backward-Facing Step: Steady-State Simulation

M.W. Siebert[1], and P.S. Fodor[1]
[1]Physics Department, Cleveland State University, Cleveland, Ohio, USA

In this work, the fluid flow over a 2D backward-facing step is analyzed in order to provide a case study for the use of different models for the blood dynamic viscosity in COMSOL Multiphysics. Three non-Newtonian models, as well as the Newtonian model are used to study the shear stresses ... En savoir plus
