3D Simulation of Laser Interstitial Thermal Therapy in the Treatment of Brain Tumors

M. Nour [1], A. Lakhssassi [1], E. Kengne [1], M. Bougataya [1],
[1] Université du Québec en Outaouais, Gatineau, QC, Canada

Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in ...

A Computational Acoustic Interrogation of Damage to Wind Turbine Blades

R. Canturk [1], M. Inalpolat [1],
[1] University of Massachusetts - Lowell, Lowell, MA, USA

Modern wind turbine blades consist of composite airfoil shaped structures that form a hollow acoustic cavity. Because of continually varying aerodynamic forces, gravitational loads, lightning strikes, and weather conditions, all blades will experience leading and trailing edge splits, ... Mehr lesen

[1] University of Tennessee, Knoxville, TN, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Introduction: The numerical solution to the neutron transport equation is employed to study a variety of problems in nuclear engineering applications, including for both eigenvalue and fixed source studies. Historically, multiphysics analysis at the HFIR has utilized these solutions to ... Mehr lesen

Modeling and Simulation of the Consolidation Behaviour of Cemented Paste Backfill

L. Cui [1], M. Fall [1],
[1] University of Ottawa, Ottawa, ON, Canada

In underground mining operations, the mined-out spaces (called stopes) need to be backfilled to maintain the stability of surrounding rock mass and increase the ore recovery. Cemented paste backfill (CPB), a mixture of water, binder, and tailings, has been intensively utilized in ... Mehr lesen

Combining Multiphysics Modeling and Solution Thermodynamics Using M4Dlib, an External Library

T. Marin-Alvarado [1],
[1] M4Dynamics, Toronto, ON, Canada

An external library, M4Dlib [1], has been developed to solve multiphysics problems coupled to solution thermodynamics. This approach extends the local equilibrium concept[2] to multiphysics modeling by incorporating a full Gibbs energy minimization routine at each numerical node to ... Mehr lesen

Development of a Thermo-Hydro-Geochemical Model for Low-Temperature Geoexchange Applications

F. Eppner [1], P. Pasquier [1], P. Baudron [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... Mehr lesen
