Heat Transfer and Phase Change

Analysis of the Absorption Phenomena through the Use of Finite Element Method

M. Robles-Agudo[1], R. Velázquez-Hernández[1], P. Duran[1], I. Rojas-Rodríguez[1]
[1]UNIVERSIDAD TECNOLÓGICA DE QUERETARO, Mexico

We present a numerical model using the Finite Element Method (FEM) with COMSOL Multiphysics® simulation software to characterize Beer-Lambert law. The Heat Transfer Module was used in the program developed to calculate absorption and propagation of heat wave phenomena in a material. ... En savoir plus

Effects of Mold-Casting Contact on Solidification in Continuous Casting

E. Gutierrez-Miravete[1]
[1]Rensselaer at Hartford, USA

This communication describes a model created to investigate the effect of mold-metal contact on casting solidification in the continuous casting process. The Heat Transfer and Solid Mechanics modules of COMSOL Multiphysics® simulation software are used to construct a non-linear finite ... En savoir plus

Assessing Reliability of Embedded Resistor Designs in Integrated Circuit

R. Wulandana[1], P. Wang[1], L. McCary[1], S. Alzeq[1]
[1]State University of New York (SUNY) at New Paltz, USA

Localized Joule heating within integrated circuit (IC) chips is the leading cause of non-uniform temperature distribution within the circuit structure of the chips. Such variation in temperature enhances the biased diffusion of metal atoms along current carrying interconnects, a ... En savoir plus

Air Space Impact on the Performance of a Solar Air Heater

M. Al-Jethelah[1], A. Al-Sammarraie[2], H. Dheyab[1]
[1]Tikrit University, Iraq
[2]University of California, Riverside, USA

Hot air is required in many engineering applications such as heating spaces and drying food. Solar air heater is used to heat air in an environmentally friendly way. The solar air heater consists of many components that are worthy to be studied to improve the performance of the solar air ... En savoir plus

High Current and Multiphysics Modeling of Carbon Fiber Reinforced Polymers (CFRP) Plates and Joints Under Lightning Strike Conditions

S. Biswas[1], M. Mirotznik[1]
[1]University of Delaware, USA

This paper presents multiphysics modeling of coupled thermal-electrical behavior across the composite joints formed by highly anisotropic conductivity materials such as carbon fiber reinforced polymers (CFRP) under lightning strike conditions and demonstrates the driving physics behind ...

Adiabatic Calorimetry of a Thermal Runaway Reaction

C. Ivory[1], M. Levin[1]
[1]Washington State University, USA

Modern adiabatic calorimeters are designed to keep thermal inertia as low as possible so that temperature-dependent reaction rates and heats of reaction can be accurately extracted from the thermocouple data. Published models of this type of equipment are generally zero dimensional (0D) ... En savoir plus

A Coupled COMSOL Multiphysics® Meshless Model for Multiscale Heat Transfer

D. Pepper[1], S. Pirbastami[1]
[1]University of Nevada Las Vegas, USA

Meshless methods are relative newcomers to the field of computational methods; the term “meshless method” refers to the class of numerical techniques that have the following advantages: (1) domain and boundary mesh discretization is not required; (2) domain integration is not required; ...

Thermal Analysis of Magnetically-Guided Cochlear Implant Surgery in a Coiled Model of the Cochlea

F. Esmailie[1], M. Francoeur[1], T. Ameel[1]
[1]UNIVERSITY OF UTAH, USA

Magnetic insertion of a cochlear implant can reduce intracochlear physical trauma by 50% compared to traditional manual insertion. The magnet attached to the tip of the cochlear implant electrode array must be detached and removed after surgery. This detachment process requires Joule ... En savoir plus
