Silent Air Cooling: A New Approach to Thermal Management

Nels Jewell-Larsen,
Tessera Technologies, CA, USA

Removing heat from electronic devices is a necessity that up until now was achieved by rotary fans. Tessera, a company that delivers innovative miniaturization technologies and products for next-generation electronic devices, developed a replacement for rotary fans that can satisfy demanding space and noise constraints. They designed a silent air cooling system that uses an electric field to ...

When it’s Impossible to Take Actual Measurements, Multiphysics Provides the Answers

Simon Chiartano,
Terres Réfractaires du Boulonnais (TRB), France

To contain splashes and provide protection at plants where metal is fabricated, blast furnace runners need a roof made of cast iron and concrete. Terres Réfractaires Du Boulonnais, a manufacturing company in France, has hundreds of blast furnaces with a short functional lifespan, so engineers need to design roof runners as economically as possible while maintaining overall safety. During the ...

Understanding the Origin of Uncertainty in Thermometer Calibration

Jonathan Pearce
National Physical Laboratory
UK

Thermometers have widespread application and like any measurement device, they must be calibrated. Many do this with the International Temperature Scale of 1990 (ITS-90), which is a platinum resistance thermometer that calibrates using a fixed point cell, which is a container with a well running through its center for insertion of the thermometer. The container has a material of 99.9999% purity. ...

Sonar Dome Vibration Analysis

Francesca Magionesi
INSEAN
Italy

There has been a recent move towards utilizing bulbous bows on ships to house different types of sonar systems, but it is not definite how much structural vibration might interfere with the functioning of a transducer array inside the sonar dome. INSEAN, the National Institute for Studies and Experiments of Naval Architecture in Italy, needed a way to simulate what is happening when the turbulent ...

Highly Accurate Li-ion Battery Simulation

Mikael Cugnet
French Atomic and Alternative Energy Commission

Battery management systems (BMSs) are designed to protect the batteries and predict their charge level. They use circuit models often derived from electrochemical impedance spectroscopy (EIS) measurements to construct an equivalent circuit model (ECM) that consists of resistors and capacitors connected both in series and in parallel. Yet, ECMs do not provide any information about important cell ...

Multiphysics Simulations Help Track Underground Fluid Movements

A. Haas, H. Mahardika, M. Karaoulis, and A. Revil
Colorado School of Mines, USA

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...

Modeling the Electrochemistry of Blood Glucose Test Strips

Stephen Mackintosh
Lifescan Scotland
UK

Lifescan Scotland is a medical device company that designs and manufactures blood glucose monitoring kits for the global diabetes market. These involve the self-monitoring of blood glucose levels through specialized monitoring systems and test strips that comprise of a plastic substrate, two carbon-based electrodes, a thin dry reagent layer, and a capillary volume where the blood is ...

Multiphysics Simulation Helps Miele to Optimize Induction Stove Designs

Christian Schröder
mieletec FH Bielefeld
Germany

Holger Ernst
Miele
Germany

The induction stove was designed to meet a consumer need for better precision and speed than traditional stoves. Designers were tasked with improving the energy efficiency of the induction coils-stovepot interaction considering both the thermal and electromagnetics of the system. Miele, a world leader in domestic appliances and commercial machines, along with researchers from mieletec FH ...

Modeling Inertial Focusing in Straight and Curved Microfluidic Channels

J. Martel and M. Toner
Biomems Resource Center
Massachusetts General Hospital
USA

N. Elabbasi, D. Quinn, and J. Bergstrom
Veryst Engineering
USA

In many medical procedures and tests, it is necessary to isolate cells of interest for further analysis. Microfluidics has revolutionized the way in which these tests are conducted enabling, for example, the ability to detect cancer from a blood sample. One of the most promising microfluidic techniques to separate and concentrate cells is called inertial focusing. The equilibrium positions for a ...

Magnets Improve Quality of High-Power Laser Beam Welding

M. Bachmann, V. Avilov, A. Gumenyuk, and M. Rethmeier
BAM Federal Institute For Materials Research and Testing
Germany

High-power laser beam welding uses a localized heat source to achieve narrow deep welds and high welding rates. Engineers run into some difficulties because the use of a localized heat source often results in the distortion of metal components; spattering and the ejection of droplets from the weld pool results in underfills, undercuts, craters, blowholes, or blowouts. A stationary magnetic field ...
