Viable design alternative for the existing and fast growing UAVs which are optimized for unmanned flight is of great demand. Designing of a small scale UAV alternative to the AAI Aerosonde UAV has been considered changing the wing tail configuration of the vehicle analyzing both structural and aerodynamic performance improvements using COMSOL Multiphysics® software.

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz and buoyancy forces are applied as volume forces to the fluid domain. Marangoni effect also is applied to the ...

Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in planning their thermal treatment doses. This will maximize therapeutic effects while minimizing side effects. ...

The goal of a tokamak is to use high magnetic fields to contain plasma and produce nuclear fusion that can be used for power generation. MIT’s Plasma Science Fusion Center (PSFC) and collaborators are proposing a machine, the Advanced Divertor eXperiment (ADX) to test new technology for these systems at reactor level heat fluxes and magnetic fields. COMSOL Multiphysics® software is used to ...

A flow and transport model in porous media was implemented in COMSOL Multiphysics® software to simulate, analyze and interpret Microbial Enhanced Oil Recovery (MEOR) processes at core scale under laboratory conditions. The flow model is biphasic and is based on the oil phase pressure and total velocity formulation in which the capillary pressure, relative permeabilities, the effects of ...

Carbon nanotube FETs are generating much interest in the nanoscale electronics area. Typically subthreshold behavior in these devices has been modeled using the Laplace equation. Above threshold behavior uses self-consistent solutions to the Poisson and continuity equations. Accurate modeling of Carbon nanotube FETs needs to include quantum effects such as tunneling. Owing to the coupled nature ...

Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, such as in the production of oil and gas, fluid viscometers, centrifugally-driven separation processes, ...

Streamers are considered as main cause of electrical breakdown in air at atmospheric pressure. A streamer is an ionization wave propagating in neutral gas which is converted into low-temperature plasma behind its front. A streamer model is based on drift-diffusion approach where space and time evolution of densities of charge carriers is considered. It results in three convection-diffusion PDEs ...

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map the tab to establish its thermal mapping. This led us to perform simulations at each ASIC of the tab that ...

In this paper, design and analysis of a novel MEMS capacitive microphone which uses corrugations and perforations in diaphragm is presented. The corrugation and perforation in diaphragm reduces the residual stress and increases the mechanical sensitivity of diaphragm. Instead of the perforated back plate, holes have been made on the diaphragm. Therefore, potassium hydroxide (KOH) etching can be ...
