Numerical Model Simulation of Impedance Based Control for RF Ablation Using Isolator Synergy Clamp
Thermal ablation is rapidly becoming a standard of care for the treatment of atrial fibrillation (AF), a cardiac disorder characterized by irregular heart rhythm and estimated to impact more than 33 million people worldwide (Chugh et al. Circulation (2013)). AtriCure is a company that ... En savoir plus
Numerical Simulation of Pool Film Boiling Heat Transfer during Quenching of Heated Cylindrical Rods
This research studies possible ways to mitigate failure of a nuclear reactor, in which the coolant supply to the nuclear core has been compromised, known as Loss of Coolant Accident (LOCA). One possible way to decrease the severity of the incident is to quickly quench the fuel rods in ... En savoir plus
Thermal Model and Control of Metal-Organic Chemical Vapor Deposition Process
Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... En savoir plus
3D Unsteady CFD with Heat and Mass Transfer Simulations of Solar Adsorption Cooling System for Buildings
In recent years, extensive attention has been paid on the application of solar cooling for buildings. Amongst cooling technologies, low-temperature solar-driven adsorption cooling systems are emerging viable alternatives to electricity-driven vapour compression systems. They seem to have ...

Simulation of a Microwave Applicator for the Treatment of Petroleum Emulsions
In Mexico there is a decline in the production of oil deposits due to the lack of effective treatment of oil emulsions, which generate a problem in the reinjection of emulsified water, transport of oil with high water content and corrosion in the oil refineries. Through the simulation ... En savoir plus
Numerical Analysis of Conjugate Heat Transfer in a Combustion Chamber and Firetubes
This paper presents the use of COMSOL's Conjugate Heat Transfer capabilities to model the coupled conduction, convection and surface-to-surface radiation heat transfer in a combustion chamber, firetube heat exchanger device. The paper details the geometry, mesh, governing equations and ... En savoir plus
Numerical Modeling of Resistive Switching in a RRAM Device
A new nonvolatile memory device based on its resistance state has emerged known as resistive random access memory (RRAM). It operates by switching between the high resistance and low resistance states which can be interpreted as logical 0 and 1 variables. Understanding the resistive ... En savoir plus
Multiphysics Modeling of Heat Transfer During Fiber Drawing
The process of cold drawing a fiber over rollers is analyzed in this work to predict the temperature rise due to the heat generated during plastic deformation of the fiber. Experimental measurements on prototypes indicated an unacceptable temperature rise of greater than 100 F requiring ... En savoir plus
Thermal Integrity Analysis of Concrete Bridge Foundations using COMSOL Multiphysics® Software
Concrete hydration is a highly exothermic process which, in large concrete structures, produces highly elevated temperatures. While this phenomenon has long been understood to be a negative side effect which can cause thermal stress cracking in concrete structures, a relatively new and ... En savoir plus
Remote Monitoring of Structures in Composite Materials via Embedded Thermo-Chemical Sensors
Composite systems are becoming more and more widespread across industries and the capability to finding and tracking internal defects before they have grown to major deterioration is of paramount importance in regard to safety, economy and maintenance. We are exploring a novel method of ... En savoir plus
