Temperature measurements of the subsurface are available due to hydrocarbon exploration in the project area, where the average drilling depth is about 2-4 km and the deepest well reaches about 8.5 km. Since the data is heavily uneven distributed, standard interpolation techniques did not deliver satisfying results. This is why numerical modeling was applied to assess the thermal regime of the ...

The MEMS microphone is also called microphone chip or silicon microphone.The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone design. The device consists of a polysilicon diaphragm suspended over a single crystal silicon backplate ...

Optimizing Fuel Cell Design with COMSOL Multiphysics

Chin-Hsien Cheng[1]
[1]Renewable Energy RD Center, Chung-Hsin Electric & Machinery, Taiwan

Proton exchange membrane fuel cells (PEMFCs) were investigated using COMSOL Multiphysics with the AC/DC Module and Chemical Engineering Module. Simulation may be used to increase the performance while decreasing the cost of the catalyst later (CL). Experimental validation of single and multi-layer CL was performed for varied PBI electrolyte content. The validated model was used to investigate ...

Simulating Thermotherapeutic Response Induced by Thermal Padding for Treating Acute Injuries

J. Kantor[1], Y. Feng[1], C. Acosta[1], E. Massingill[1]
[1]University of Texas at San Antonio, San Antonio, TX, USA

Cryotherapy and thermotherapy are common methods of treatment for acute injuries ranging from ankle sprains to complex surgery. The idea behind such treatment is that a change in temperature will reduce pain and constrict fluctuations in blood flow at the targeted area. The purpose of this study is to simulate the vascularized tissue reaction and the resulting blood flow fluctuation from thermal ...

Multiphysics Analysis of Normal Conducting RF Cavities for High Intensity Proton Accelerators

M. Hassan[1], I. Gonin[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermi National Accelerator Laboratory, Batavia, IL, USA

Normal conducting cavities are typically used in the front end of proton accelerators to get the beam accelerated to velocities approximately a few tenths of the speed of light, where superconducting cavities can then be used to accelerate the beam to the speed of light. The warm part of a typical proton accelerator would contain a radio frequency quadrupole (RFQ) and several buncher cavities. ...

COMSOL Multiphysics for the Designs and Applications on Biomicrofluidic Chips

I-Fang Cheng[1]
[1]National Nano Device Laboratories (NDL), National Applied Research Laboratories, Taipei, Taiwan

Some types of rare pathogens can be detected and identified in human blood through a low-cost and label-free method. The On-Chip SESR identification process has a fast detection time (about 5 minutes) and a low detection limit. Discrimination of a species is done by sorting red blood cells from bacteria. Simulations of dielectrophoretic (DEP) force, dual layer electrodes, and dynamic separation ...

Water Quality Modeling of Drinking Water Storage Reservoir Noardburgum

N. Wolthek[1]
[1]Vitens NV, Zwolle, The Netherlands

The water storage reservoir at the WTP Noardburgum is used to even out demand and supply and ensure a stable drinking water production capacity. At the moment the rectangular reservoir has a single pipeline which serves as an inlet during the fill cycle and as an outlet during the draw cycle. This study aims to examine the current mixing characteristics of the reservoir and to investigate ...

Modelling of a 5 Cell Intermediate Temperature Polymer Electrolyte Fuel Cell (IT-PEFC) Stack: Analysis of Flow Configuration and Heat Transfer

[1]Centre for Hydrogen and Fuel Cell Research, University of Birmingham, Birmingham, United Kingdom
[2]University of Birmingham, Birmingham, United Kingdom

Polymer Electrolyte Fuel Cells (PEFCs) are a key technology in the advancement of society towards a low carbon future, in particular for use within the automotive sector. PEFCs are advantageous due to their low operating temperature (60-80 deg.C), quick start up times and responsiveness to load change. However, the requirement for expensive platinum, difficulty of water management and heat ...
