Numerical and Experimental Studies of a Capillary Channel

M. Xu[1], Z. Wu[1], X. Wang[1]
[1]Tsinghua University, Beijing, China

Capillary effects are common in microfluidics due to large surface-to-volume ratio of flows inside microchannels. In biological or chemical analysis, capillary flow is used for the transport of liquid and mixing enhancement, without applying any external means. It’s used in biochemical ... Read More

Simulation of Cellular Traction Force Based Deflection of PDMS Micropillars

J. Wala[1], D. Maji[1], S. Dhara[1], S. Das[1]
[1]Indian Institute of Technology Kharagpur, Kharagpur, West Bengal, India

Cells are complex entities which not only passively sense external stimuli (viz. chemical, optical or mechanical) but also interact with extracellular matrix (ECM) by regulating cellular behavior such as growth, proliferation, migration, etc. Monitoring cell growth and migration of ... Read More

3D Modelling of Flow Dynamics in Packed Beds of Low Aspect Ratio

F. Alzahrani[1], F. Aiouache[1]
[1]Engineering Department, Lancaster University, Lancaster, UK

This work used the 3D CFD modeling to investigate non-uniform deactivation in packed bed reactors of low aspect ratios under steady state and dynamic operations. In order to explore the effects of condition of instability on local deactivation, detailed knowledge of flow dynamics (i.e. ... Read More

An Improved Loudspeaker Frequency Response by Using a Structure of Rigid Absorptive Panel in a Vented Cabinet

R. Balistreri[1]
[1]Community Light & Sound Inc., Chester, PA, USA

When placing a loudspeaker in a cabinet, standing waves inside the cabinet affect the frequency response with ripples. This peaks and dips due to pressure cancellation inside the cabinet have an effect on the diaphragm and generating sound out from the vents. If it was in a condition of ... Read More

Modeling of Directional Dependence in Nanowire Flow Sensor

A. Piyadasa[1,3], P. Gao[1,2,3]
[1]Department of Physics, University of Connecticut, Storrs, CT, USA
[2]Department of Materials Science & Engineering, University of Connecticut, Storrs, CT, USA
[3]Institute of Materials Sciences, University of Connecticut, Storrs, CT, USA

3D finite element analysis model has been constructed for testing the directional dependence in a novel form of nanowire array gas flow sensor. Single nanowire (p-type single crystal Silicon) model is developed using fluid structure interaction and piezoresistivity components in the MEMS ... Read More

COMSOL Multiphysics® Based Identification of Thermal Properties of Mesoporous Silicon by Pulsed Photothermal Method

N. Semmar[1], I. El Abdouni[1], A. Melhem[1]
[1]GREMI-UMR7344, CNRS/University of Orléans, Orléans, France

The silicon is mainly known under its single-crystal shape and polycrystalline. Since a few decades, a new type of morphology is developed: the porous silicon (p-Si). Meso-porous silicon (Mp-Si) is one of promising materials for future microelectronic chips multi-functionalization ... Read More

Characterization of the Process of Ultrasound Driven Dispersion of Nanoparticles in High Viscosity Liquids

P. Pasumarty[1], H. Choi[1]
[1]Clemson University, Clemson, SC, USA

Even though sonochemical reactors have been studied extensively for decades, there is limited data on their characterization when the volume of the sample is fixed. The Acoustics Module and COMSOL Multiphysics® software are used to resolve the pressure field. The validated numerical ... Read More

Modeling Heat and Moisture Transport During Hydration of Cement-Based Materials in Semi-Adiabatic Conditions

E. Hernandez-Bautista[1,2], D. Bentz[1], S. Sandoval-Torres[2], P. Cano-Barrita[2]
[1]National Institute of Standards and Technology, Gaithersburg, MD, USA
[2]Instituto Politécnico Nacional/CIIDIR Unidad Oaxaca, Oaxaca, México

The process of accelerated curing of pre-cast concrete has a significant importance in the thermal behavior of concrete. A multiphysics model that describes hydration and heat and mass transport in cement based materials was developed. The hydration reactions are described by a maturity ... Read More

CFD Simulation of Internal Flow Field of Dual-mode Scramjet

C. Butcher[1], K. Yu[1]
[1]University of Maryland, College Park, MD, USA

The complex internal flow field of a hypersonic air-breathing propulsion engine was modeled using COMSOL Multiphysics® software. This type of flow field can be found in a dual-mode scramjet engine. After creating the geometry, a 2D CFD simulation was run using the High Mach Number Flow ... Read More

Strong Localization and Rapid Time Scales of Superheating in Solid-State Nanopores

E. Levine[1], G. Nagashima[1], D. Hoogerheide[1], M. Burns[2], J. Golovchenko[1]
[1]Harvard University, Cambridge, MA, USA
[2]Rowland Institute at Harvard University, Cambridge, MA, USA

Extreme localized superheating and homogeneous vapor bubble nucleation have recently been demonstrated in a single nanopore in thin, solid state membranes [1]. Aqueous electrolytic solution present within the pore is superheated to well above its boiling point by Joule heating from ionic ... Read More
