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

Fluid-Structure Interaction of a Double Curvature Arch Dam Under Seismic Loading by the Application of Added Mass Technique and Acoustic Elements

R. Manikandan[1], P. Sultana[1]
[1]National Institute of Technology Silchar, Silchar, Assam, India

Fluid Structure Interaction (FSI) plays an important role in the seismic analysis and the design of Hydraulic structures. In this study, the acoustic finite element model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream ... En savoir plus

Numerical Study of Smoldering Combustion of Activated Carbon in Ⅱ Iodine Absorber

T. Liang[1], M. Liu[1], X. Liu[1], Z. Meng[1]
[1]Safety Engineering, Zheng Zhou University, Zheng Zhou, Henan, China

Iodine absorber is a widely used purification equipment for purifying air in a nuclear power plant. In China, the common type is Ⅱ iodine absorber. Impregnated activated carbon is the main absorber within the iodine absorber. Because of the decays exothermic of radioactive iodine, heat ... En savoir plus

H. Garg[1], V. S. Negi[1], A. S. Kharola[1], R. Sharma[1]
[1]CSIR - Central Scientific Instruments Organization, Chandigarh, India

Magnetorheological Finishing (MRF) is one of the precision finishing processes in which magnetic field is used to drive abrading forces for Finishing 2D and complex 3D surfaces. In this paper, Ball End Magnetorheological Finishing (BEMRF) has been analyzed for fluid behaviors under the ... En savoir plus

Hydrodynamic Flow Focusing for Microfluidic Cell Sorting Chip

N. Mehendale[1], D. Paul[1]
[1]Indian Institute of Technology Bombay, Mumbai, Maharashtra, India

Hydrodynamic flow focusing is an important requirement of microfluidic cell sorting devices. It allows the cells to arrive sequentially at the sorting location making detection easier. The simplest flow focusing configuration uses a three input Y-shaped microchannel. The sample enters ... En savoir plus

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... En savoir plus
