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 ... Read More

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) ... Read More

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 ... Read More

Finite Element Modeling of Beam Deflection in Photothermal Deflection Spectroscopy

M. Kline[1], P. Nichols[1], J. Pedroza Ramirez[1], S. Johnson[1]
[1]Transylvania University, USA

Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... Read More

Experimental and Numerical Evaluation of Metal Foam Thermal Performance Interacting with Nanofluid: Applications in Electronics Cooling

C. Welsford[1], C. Delisle[1], Z. Saghir[1]
[1]Ryerson University, Canada

The present study aimed to determine the effect of nanofluid concentration, channel inclusion, flow rate, and heat flux, on the thermal effectiveness of Al2O3 nanofluid and 6061-T6 aluminum foam metal with 91% porosity and 40 linear pores per inch as components in a heat exchange system ...

Finite Element Analysis of Chemical Reaction Kinetics and Transport Phenomena of a Solid State Combustion Synthesis

S. Lin[1], V. Doddapaneni[1]
[1]Lamar University, USA

A 3D unsteady state chemical reaction system was modeled using COMSOL Multiphysics® simulation software. In this work, the Chemical Reaction Engineering Module was integrated to calculate physical, chemical and thermodynamic properties and transport phenomena. Advanced materials such as ... Read More

Thermo-Acoustic Simulation of a Piezoelectric Transducer for Interstitial Thermal Ablation with MRTI Based Validation

K. Gandomi[1], P. Carvalho[1], Z. Zhao[1], C. Nycz[1], E. Burdette[2], G. Fischer[1]
[1]Worcester Polytechnic Institute, USA
[2]Acoustic Med Systems, USA

The five year survival rate for malignant brain and central nervous system cancer was estimated at 35% between 2000 and 2015. Deep brain tumors can be unsuited for conventional surgical intervention. One minimally invasive treatment option is interstitial needle-based therapeutic ... Read More
