Poroelastic Models of Stress Diffusion and Fault Re-Activation in Underground Injection

R. Nopper[1], J. Clark[2], C. Miller[1]
[1]DuPont Company, Wilmington, DE, USA
[2]DuPont Company, Beaumont, TX, USA

Stress and failure in the earth have long been observed to couple to hydrogeology. Poroelastic models, introduced by soil scientists, can account for strong two-way coupling between porous crustal rock formations and their pore fluids. Current efforts to provide new energy resources ... En savoir plus

Simulation of Electro-Thermal Transients in Superconducting Accelerator Magnets

[1] CERN, Geneva, Switzerland
[2] CERN, Geneva, Switzerland; Lodz University of Technology, Lodz, Poland
[3] CERN, Geneva, Switzerland; Paul Scherrer Institute, Zurich, Switzerland

The paper presents the application of COMSOL Multiphysics® software to the modelling of superconducting accelerator magnets. A 2D magneto-thermal model is developed, using an equivalent magnetization formulation to take into account the eddy-currents’ effects. Due to the model ... En savoir plus

Numerical Investigation of Micronozzle Performance for Various Nozzle Geometries

P. A. Haris[1], T. Ramesh[1]
[1]National Institute of Technology Tiruchirappalli, Tiruchirappalli, Tamil Nadu, India

Design and manufacture of thrusters for producing very low thrust force in the range of milli or micro newtons using micronozzles has been actively developed in the last decade. The nature of propellant flow in such micronozzles differs from that of macro nozzles. In micronozzles, ... En savoir plus

Modeling System Dynamics in a MEMS-Based Stirling Cooler

D. Guo, A. McGaughey, G. Fedder, M. Lee, and S. Yao
Carnegie Mellon University
Pittsburgh, PA

Micro-scale devices based on the Stirling cycle are an attractive choice for chip- and board-level electronics. A new Stirling cycle micro-refrigeration system composed of arrays of silicon MEMS cooling elements has been designed. COMSOL is used to evaluate the thermal performance of ... En savoir plus

Modelling Aircraft Fuel Gauging Unit using COMSOL Multiphysics Software

T. Ekwevugbe[1], and G. Bevan[2]
[1]Institute of Energy and Sustainable Development, De Montfort University, Leicester, United Kingdom
[2]School of Engineering and Computing, Glasgow Caledonian University, Glasgow, Scotland

An investigation was undertaken into the suitability of using COMSOL for modeling an aircraft capacitive fuel gauging unit. A model of a sensor immersed in a fluid was developed for rectangular tank geometry with a range of fluid levels and sensor orientation using the electrostatics ... En savoir plus

Multiphysics Modelling of a Micro Valve

F. Bircher[1] and P. Marmet[1]

[1]Institute of Print Technology, Bern University of Applied Sciences, Burgdorf, Switzerland

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... En savoir plus
