Multiphysics Simulation of a Printed Circuit Heat Exchanger

A. Daouk [1], O. E. Petel [1], H. Saari [1],
[1] Carleton University, Ottawa, ON, Canada

Compact Heat Exchangers, specifically Printed Circuit Heat Exchangers, are widely used in industry as a replacement for traditionally large heat exchangers (e.g. Shell and Tube) due to their small size and high effectiveness. Modelling of PCHEs, specifically those manufactured by Heatric ... Read More

Numerical Modeling of 3D Electrowetting Droplet Actuation and Cooling of a Hotspot

M. M. Nahar [1], H. Moon [1], G. S. Bindiganavane [1], J. Nikapitiya [1]
[1] Department of Mechanical and Aerospace Engineering, University of Texas - Arlington, Arlington, TX, USA

Electrowetting on Dielectric (EWOD) is a versatile tool for performing basic operations in Digital Microfluidic Systems. In EWOD, surface tension between a liquid droplet and solid substrate is modulated by applying voltage to an electrode and a hydrophobic surface is transformed into a ... Read More

Multiphysics Model for Breakup of Charged Liquid Droplets in Electric Fields

S. Chaudhuri [1], W. Du [1],
[1] University of Illinois at Urbana-Champaign, Champaign, IL, USA

Predicting and controlling the formation of droplets from a liquid jet is a critical problem in a variety of applications ranging from fuel injection to paint sprays. It is known that liquid droplets subjected to an electric field acquire a net electrostatic charge via induction, and ... Read More

COMSOL Multiphysics® Software Simulation of a Dual-axis MEMS Accelerometer with T-Shaped Beams

C. Zheng [1], X. Xiong [1], J. Hu [2]
[1] Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT, USA
[2] Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA

Introduction: Inertial navigation requires acceleration measurement along all three degree-of-freedoms. Most accelerometers are designed to measure acceleration along a single sensitive direction. For complete inertial sensing, a move effective accelerometer which can sense ... Read More

Simulation of the Geometric Design Parameters’ Impact on the Performance of EHD Ion-Drag Micropump

M. Badran [1],
[1] Future University in Egypt, New Cairo, Egypt

A two-dimensional numerical simulation study has been performed to model an electrohydrodynamic (EHD) micropump. The emphasis of this study was on simulating the effect of the different geometric design parameters on the micropump pressure head and volume flow rate. The simulated design ... Read More

Simulation of Sample Inhomogeneity in Microwave Impedance Microscopy

T. S. Jones [1], C. R. Pérez [1], J. J. Santiago-Avilés [1],
[1] University of Pennsylvania, Philadelphia, PA, USA

Microwave impedance microscopy (MIM) is a novel mode of atomic force microscopy that can measure topography and local electrical impedance simultaneously and with nanometer spatial resolution [1]. This technique is typically used qualitatively, identifying defects in nanodevices or ... Read More

CFD Modeling for the Ventilation System of a Hospital Room

A. Kermani [1],
[1] Veryst Engineering LLC, Needham, MA, USA

Indoor ventilation with good air quality control prevents infection with minimizing the spread of airborne respiratory and other infections in hospitals. CFD can be utilized to optimize flow pattern in clean rooms especially hospital clean rooms. More than two million people in Europe ... Read More
