A Computational Approach for Optimizing the First Flyer Using COMSOL Multiphysics

A.H. Aziz[1], H. Pourzand[1], A.K. Singh[1]
[1]Pennsylvania State University, University Park, PA, USA

COMSOL Multiphysics software was used to structurally optimize the Wright brothers’ flyer. The flyer was drawn in SolidWorks, imported and meshed in COMSOL. COMSOL Solid Mechanics module was used to analyze the flyer. Four of the sixteen struts were removed yet the structural integrity of the flyer was maintained. COMSOL Laminar Flow module was used to compute the aerodynamic forces and ...

Undergraduate Studies of Supersonic Flow from a Converging-Diverging Nozzle

K. Stein[1], N. Gessner[1], R. Peterson[1], A. Wiedmann[1]
[1]Department of Physics, Bethel University, St. Paul, MN, USA

Undergraduate studies are carried out to examine the supersonic flow from an axisymmetric converging-diverging nozzle. Flow in the nozzle is initiated by the rupture of a diaphragm that is positioned between the nozzle and a 1-gallon pressurized air tank. Simulations are carried out in COMSOL Multiphysics® for unsteady, axisymmetric flow with the High Mach Number interface of the CFD Module. ...

Multiphysics Modelling in the Electromagnetic Levitation and Melting of Liquid Metals

A. A. Roy, V. Bojarevics, and K. Pericleous
University of Greenwich
London, UK

The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation tool have been generated to two industrial problems using the ALE moving-mesh module in combination with the ...

Metal Foam Tube Flow Characterisation

T. Spillmann[1]
[1]CSIRO, Energy Technology, Newcastle, New South Wales, Australia

In this study the flow through a tube filled with highly porous aluminium foam of three different pore sizes is analysed using COMSOL Multiphysics® CFD Module and compared to experimentally determined pressure drop data. Analyzing the flow through an array of pores allow the deduction of characteristic flow parameters (permeability and form drag coefficient) that are utilized in a 2D ...

Investigating the Impacts of Hydrogeological Parameters on DSI Efficiency through Numerical Simulation

[2]Hölscher Wasserbau, Haren, Germany

Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same borehole, but in greater depth. We use COMSOL Multiphysics® for the development of a 2D model that simulates ...

Modelling of the Wool Textile Finishing Processes

M. Giansetti[1], A. Pezzin[1], S. Sicardi[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

Within wool textile industries, a very important role is played by the so-called finishing processes, in which the textile substrate undergoes steam treatments to achieve the desired level of stabilisation and appearance. Process parameters, namely temperature and moisture content, are known only at the beginning of the process but not in the textile material being treated, where the actual ...

CO2 Storage Trapping Mechanisms Quantification

A. Nardi[1], E. Abarca[1], F. Grandia[1], J. Molinero[1]
[1]Amphos 21, Barcelona, Spain

The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. In general, four trapping mechanisms are expected, which are of increasing importance through time: (1) structural, (2) residual ...

Modeling the Effect of Headspace Steam on Microwave Heating of Mashed Potato - new

J. Chen[1], K. Pitchai[1], D. Jones[1], J. Subbiah[1]
[1]University of Nebraska-Lincoln, Lincoln, NE, USA

Introduction: Domestic microwave ovens are widely used to heat food products, because of rapid and convenient heating. Nonuniform heating is the biggest issue in microwave heating process, which also causes food quality and safety issues. Microwave heating models are promising tools to assist in developing food products that deliver uniform heating. Due to intensive heating, moisture evaporation ...

Virtual Functional Product Development of a µ-Methane Steam Reformer

T. J. Kazdal [1], M. J. Hampe [1],
[1] Technische Universität Darmstadt, Darmstadt, Germany

A micro steam methane reformer is a complex product consisting of multiple units. For the virtual functional product development it is necessary to validate these sub models separately. Therefore a reactor was designed to analyse kinetics of chemical reactions. The reactor design is based on a simulation geometry and the boundary conditions of the simulation were recreated in the experimental ...

Mathematical Modeling Of Traveling-Wave Electroosmotic Micropumps By Using Of The Weak Form

J. Hrdlicka, P. Cervenka, and D. Snita
Institute of Chemical Technology Prague, Prague, Czech Republic

This contribution is devoted to the mathematical modeling of the AC electroosmotic micropumps in COMSOL Multiphysics and Matlab. The mathematical model involves the microchannel surroundings and several AC-voltage driving modes. The weak form has been used for handling singularities and other problems. The system dynamic behavior and conditions at the phase interfaces will be discussed.
