Analyzing Muffler Performance Using the Transfer Matrix Method

K. Andersen
Dinex Emission Technology A/S, Middelfart, Denmark

Exhaust noise must meet legislation targets, customer expectations and cost reduction which call for design optimization of the exhaust systems in the design phase. One solution is to use 3 dimensional linear pressure acoustics and calculate the transfer matrix of the muffler. The ... En savoir plus

[2] National Institute of Laser, Plasma and Radiation, Măgurele, Romania

The radio-frequency(RF) plasma sources have shown great potential in various industrial applications such as thin coatings deposition and polymers modification[1,2]. Physics of low pressure RF plasmas has been investigated significantly[3]; however, this kind of plasma source is rarely ... En savoir plus

FSI Analysis of Microcantilevers Vibrating in Fluid Environment

A. Ricci[1] and E. Giuri[1]

[1]Materials and Microsystems Laboratory (CHI-Lab), Politecnico di Torino, Torino, Italy

Cantilever vibration in fluid environment is probably one of the most common Fluid Structure Interaction problems in the field of Micro/Nano Electro Mechanical Systems. Usually the effect of fluid on cantilever oscillation is characterized in terms of mode resonance frequencies and ... En savoir plus

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 ... En savoir plus

Energy Harvesting in a Fluid Flow Using Piezoelectric Materials

M. Curatolo [1], M. La Rosa [1], P. Prestininzi [1],
[1] Roma Tre University, Rome, Italy

Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... En savoir plus

Simulation of a Diesel Oxidation Catalyst Used in a NO_x Storage and Reduction system for Heavy Duty Trucks

C. Odenbrand, and E. Senar Serra
Department of Chemical Engineering, Lund University, Lund, Sweden

This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic ...

Electrophoretic Focusing and Navigation for Intranasal Target Drug Delivery

X. Si[1]
[1]Calvin College, Grand Rapids, MI, USA

Direct nose-to-brain drug delivery circumvents the blood-brain-barrier and has multiple advantages over intravenous delivery. However, its application is limited by the extremely low delivery efficiency to the olfactory region. This study evaluated the feasibility of targeted drug ... En savoir plus

A Modular Platform for Cell Characterization, Handling, and Sorting by Dielectrophoresis

S. Burgarella[1], B. Dell’Anna[2], V. Perna[1], G. Zarola[2], and S. Merlo[2]

[1]STMicroelectronics, Agrate Brianza, MI, Italy
[2]Dipartimento di Elettronica, Università degli Studi di Pavia, Pavia, Italy

Dielectrophoresis (DEP) is a method for cell manipulation without physical contact in lab-on-chip devices, since it exploits the dielectric properties of cells suspended in a microfluidic sample, under the action of locally generated high-gradient electric fields. The DEP platform that ... En savoir plus
