A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air velocity and temperature. The model has a good agreement with experimental data for the photovoltaic cell ...

Human made mechanical resonators have been around for a thousand years. Early applications included musical instruments and chronographs operating in millihertz to kilohertz frequencies while more recent interest has turned ultra-high frequency resonators and oscillators suitable for wireless technologies, mass sensing and even biological applications. The trend has been towards small, stiff and ...

Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this research, polymeric microspheres containing biodegradable poly(D, L-lactide-co-glycolide) (PLGA), magnetic ...

Combustion instability in solid rocket motors and liquid engines has long been a subject of concern. Recent advances in energy based modeling of combustion instabilities require accurate determination of acoustic frequencies and mode-shapes. Of particular interest is the acoustic mean flow interactions within the converging section of a rocket nozzle, where gradients of pressure, density, and ...

This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high-doped constriction region, and the high-doped leg region) is solved using the general heat transfer module for DC ...

The rapid development of electronic devices leads to more demand for efficient cooling techniques. Porous media represent a convincing passive cooling enhancer due to its large contact surface area to volume ratio and intense mixing of ﬂuid ﬂow. In the present work, numerical studies have been investigated to study the heat transfer characteristics of aluminum porous metal foam subjected to ...

The major steps in the beer making process are simple and with some skill, rather good brew can be produced using a common picnic cooler. First, grain (usually barley) is wetted and allowed to partially germinate before dried in a kiln (malting) Next, during mashing in a mash tun reactyor the malted grains are soaked in hot water in to extract the fermentable sugars and then rinsed slowly to ...

A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...

We simulated the diffusion of calcium ions through a nanopore created in the cell membrane by electroporation, in presence and absence of the external electric field responsible of the membrane permeabilization. First we solved the set of coupled differential equations that describe the process of ionic diffusion in a 2D nanopore model using the AC/DC Module and the Transport of Diluted Species ...

COMSOL® software was used to simulate the conductive heat transfer with phase change in the geological formations encompassed in permafrost surrounding a shallow thaw lake. The purpose of the simulation was to verify the adequacy of COMSOL to model such phenomena by comparing the COMSOL results to those obtained by another FEM model (Ling and Zhang, 2003). The graphical comparison of the ...
