Fluid Dynamics Analysis of Gas Stream in a Plasma Torch Reactor

C. Soares[1], N. Padoin[1], F. A. Cassini[1], M. Sanchez[2]
[1]Federal University of Santa Catarina, Florianópolis, SC, Brazil
[2]University of Oklahoma, Norman, OK, USA

Plasma technology has potential applications in a wide range of areas, such as microwave reflectors/absorbers, material processing, sterilization and chemical neutralization. The knowledge about the fluid behavior in such systems has a central role, since the stability of the flow in the ... En savoir plus

Performance of a Miniaturized Hydrocyclone for the Isolation of Schistosoma Mansoni Eggs

C. Soares[1], N. Padoin[1], F. Montalvo[2], D. Cobra[2]
[1]Federal University of Santa Catarina, Florianópolis, SC, Brazil
[2]CERTI Foundation, Florianópolis, SC, Brazil

Schistosoma mansoni parasites affect million people worldwide. The intensity of the infection can be evaluated by the number of eggs present in the stool of an infected individual. The application of the traditional methods has been regarded as impractical in developing areas and there ... En savoir plus

In this study, COMSOL Multiphysics® software was applied to the investigation of the electromagnetic behavior of an optical crystal submitted to the magnetic field generated by electric current in a near positioned metallic conductor. Moreover, the influence of a ferromagnetic apparatus ... En savoir plus

An Approach to Modeling Vacuum Desorption

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... En savoir plus

Princípio Calorimétrico Aplicado a Medição de Vazão

Introdução: A medição adequada de vazão de fluidos é de grande importância nos processos industriais, pois tem implicações diretas na qualidade, produtividade, segurança e eficiência dos processos. Assim, torna-se necessário compreendermos como os fluidos se comportam para baixas ... En savoir plus

Analysis of 1D, 2D, and 3D Marine CSEM in COMSOL Multiphysics® Software

E. C. Luz[1]
[1]Universidade Federal do Pará, Belém, PA, Brazil

The Marine Controlled Source ElectroMagnetic (marine CSEM) is a geophysical method used by the oil industry to investigate resistive targets in the sediments under the ocean floor. In this work we simulate marine CSEM data including 1D, 2.5D and 3D modeling. The results obtained with ... En savoir plus

Simulation of 2D Photonic Crystal With COMSOL Multiphysics® Software

Z. Liang[1], Z. Meng[2], K. Jie[1], Y. Benxi[1]
[1]Institute of Optics and Electronics, Chinese Academy of Sciences, Chengdu, China
[2]Institute of Semiconductors, Chinese Academy of Sciences, Beijing, China

This paper introduces the concept, research methods and application of photonic crystals. Starting from Maxwell's equations, the functional form of the TE mode and TM mode of the 2D crystal is derived. In 2D crystal, according to the functional forms, we conduct some stimulation about ...

Simulation of a Voltage Controlled Resistor Mimicking the Geometry of a MOSFET Device with Graphite Channel

M. Bhattacharjee[1], N. Mandal[1], H. B. Nemade[1], D. Bandyopadhyay[1]
[1]Indian Institute of Technology Guwahati, Guwahati, Assam, India

A Voltage Controlled Resistor (VCR) is simulated by replacing the semiconductor channel of a MOSFET device by graphite and embedding Si nanoparticles near the insulator-channel interface. The change in output drain current is found to depend on the thickness and relative permittivity of ... En savoir plus

Numerical Modeling of the Near-Subsurface Temperature Distributions in the Presence of Time Varying Air Temperature in the Boundary Condition and Space Varying Temperature for the Initial Condition

M. Ravi[1], D. V. Ramana[1], R. N. Singh[1]
[1]CSIR - National Geophysical Research Institute, Hyderabad, Telangana, India

The subsurface thermal structure in presence of groundwater recharge/discharge has been obtained by applying the Robin type boundary condition at the earth’s surface. The Robin type boundary condition involves the effect air temperatures at the surface which are taken as exponentially ... En savoir plus

FEM Analysis of Flamelet Wrinkling in a Diffusion Flame

Y. Li[1], T.C. Lieuwen[2], J. Zhou[1], H. Cao[1]
[1]Zhengzhou University, Zhengzhou City, Henan Province, China
[2]Georgia Institute of Technology, Atlanta, GA

One can hardly get the exact analytic solution of a full time-dependent convection-diffusion equation, for describing the dynamics of a non-premixed flamelet. The analytic solution of the linearized form with such a model was studied by MATLAB®. And also, a numerical computation was made ... En savoir plus
