Design and Stress Analysis of a General Aviation Aircraft Wing

G. Atmeh[1], F. Darwish[1], and Z. Hasan[2]
[1]Jordan University of Science and Technology, Irbid, Jordan
[2]Texas A&M University, College Station, TX, USA

The present study focuses on the design and analysis of a single-engine, propeller-driven general aviation airplane. Initial weight estimation based on the initial sketch and the design mission profile is conducted. The estimated weight and other design parameters are used to define the ... Читать дальше

Analysis of Burning Candle

J.S. Crompton, L.T. Gritter, S.Y. Yushanov, and K.C. Koppenhoefer
AltaSim Technologies LLC, Columbus, OH, USA

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle ... Читать дальше

Implementation of the Perfectly Matched Layer to Determine the Quality Factor of Axisymmetric Resonators in COMSOL

M.I. Cheema, and A.G. Kirk
McGill University, Montreal, QC, Canada

Due to the inseparability of the wave equation, numerical methods are needed to develop an accurate electromagnetic model for various axisymmetric resonators such as micro-discs and micro-toroids. Our purpose is the implementation of a perfectly matched layer to determine the quality ... Читать дальше

COMSOL Multiphysics-Based Exploratory Insulin Secretion Model for Isolated Pancreatic Islets

P. Buchwald
University of Miami, Miami, FL, USA

Insulin released by the beta-cells of pancreatic islets is the main regulator of glucose homeostasis, hence, insulin secretion models are of considerable interest for many possible applications. Building on our previous oxygen consumption and cell viability model for avascular islets of ... Читать дальше

Simulating the Electrical Double Layer Capacitance

G. Zhang
Clemson University, Clemson, SC, USA

When a solid surface makes contact with a liquid medium, an electrical double layer (EDL) structure forms spontaneously through thermodynamic interaction between electrons and ions. In this study, we developed a computational model using commercial finite element analysis package COMSOL ... Читать дальше

Dynamic Structural Modelling of Wind Turbines Using COMSOL Multiphysics

C. Van der Woude, and S. Narasimhan
University of Waterloo, Waterloo, ON, Canada

This paper presents a study of a wind turbine subjected to wind and seismic loading, carried out using COMSOL Multiphysics. The dynamic properties and response of wind turbine structures are of interest, as recent developments in wind energy have led to the design and construction of ... Читать дальше

Stefan's Problem: Validation of a One-Dimensional Solid-Liquid Phase Change Heat Transfer Process

D. Groulx, and W. Ogoh
Dalhousie University, Halifax, NS, Canada

A 1D phase change problem, known as Stefan’s problem, for which analytical solutions are available, is solved as a 2D problem using COMSOL Multiphysics. The PCM medium is semi-infinite, initially solid at its melting temperature Tm, and at t = 0, the wall temperature is raised to Tw > ... Читать дальше

COMSOL Assisted Simulation of Laser Engraving

H. Karbasi
Conestoga College, Kitchener, ON, Canada

The main purpose of this paper is to develop a proof of concept software that can simulate the geometry of engraved surfaces and can estimate the depth and width of engraved groove and associated laser parameters. For this purpose, COMSOL has been used to simulate the moving laser ... Читать дальше

Modeling Horizontal Ground Heat Exchangers in Geothermal Heat Pump Systems

A. Chiasson
University of Dayton, Dayton, OH, USA

Geothermal heat pumps use the earth as a heat source and sink via a ground heat exchanger (GHX) that consists of a network of buried heat exchange pipes, which can either be installed in vertical boreholes or in shallow horizontal trenches or excavations. The main goal in GHX design is ... Читать дальше
