Evaluation of mesoporous silicon thermal conductivity by electrothermal finite element simulation
The aim of this work is to determine the thermal conductivity of mesoporous silicon (PoSi) by fitting the experimental results with simulated ones. The electrothermal response (resistance versus applied current) of differently designed test lines integrated onto PoSi/silicon substrates and the bulk were compared to the simulations. The PoSi thermal conductivity was the single parameter used to ...
متن کاملOn the Thermal Conductivity of Carbon Nanotube/Polypropylene Nanocomposites by Finite Element Method
In this paper, finite element method is used to obtain thermal conductivity coefficients of single-walled carbon nanotube reinforced polypropylene. For this purpose, the two-dimensional representative volume elements are modeled. The effect of different parameters such as nanotube dispersion pattern, nanotube volume percentage in polymer matrix, interphase thickness between nanotube and surroun...
متن کاملSimulation of a Microgripper with Electrothermal Actuator Using COMSOL Software Based on the Finite Element Method
Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...

متن کاملMonte Carlo Simulation of Silicon Nanowire Thermal Conductivity
Monte Carlo simulation is applied to investigate phonon transport in single crystalline Si nanowires. Phonon-phonon normal N and Umklapp U scattering processes are modeled with a genetic algorithm to satisfy energy and momentum conservation. The scattering rates of N and U scattering processes are found from first-order perturbation theory. The thermal conductivity of Si nanowires is simulated ...
