CFD Analysis of Ejectors

Vikas N Bhargav[1], Vivek Ganeshan[1], Muralidhara Holla[1], Ramesh Kolluru[1]
[1]Mechanical Engineering Department, BMS College of Engineering, Bangalore, India

Ejectors are the devices used to carry out mixing and recompression of two fluid streams, one with higher energy and the other with lower Energy. The high energy fluid is passed through the converging nozzle of ejector to very high velocities which in turn creates suction and draws the ... En savoir plus

Wireless Power and Communications for Implantable Biosensors

C. Romero[1], M. Mujeeb-U-Rahman[1]
[1]California Institute of Technology, Pasadena, CA, USA

Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely ... En savoir plus

Low Reynolds Number Flow Around a Flying Saucer Micro Air Vehicle

S. Cortés[1], D. Güemes[1], R. Ávila[1]
[1]Universidad Nacional Autónoma de México, Mexico City, Mexico

The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we ... En savoir plus

Impact of a 3D EM Model Configuration on the Direct Optimization of Microstrip Structures

Z. Brito-Brito[1], J. E. Rayas-Sánchez[1], J. C. Cervantes-González[2], C. A. López[2]
[1]The Jesuit University of Guadalajara. Dept. of Electronics, Systems and Informatics, Jalisco, México
[2]Intel Guadalajara Design Center, Jalisco, México

The EM optimization of a coarsely discretized model of a microstrip band-pass filter implemented in COMSOL Multiphysics® was realized using two different model configurations. We presented a systematic methodology to find an appropriate 3D EM model configuration on a direct EM ... En savoir plus

Models with Helical Symmetry Studied in a 2D Plane

M. Weterings[1], M. Beyrer[1]
[1]Institute of Life Sciences HesSo Valais, Sion, Valais, Switzerland

Partial differential equations (PDEs) in multiple dimensions may often be solved in a lower dimension if the problem domain contains a symmetry (cylindrical, spherical, translational, etcetera). For problems involving PDEs with helical symmetry we propose a method, with both low ... En savoir plus

Numerical Simulation of the Effect of Inlet Design on Thermal Storage Tank Performance Using COMSOL Multiphysics®

W. Yaïci[1], M. Ghorab[1], E. Entchev[1]
[1]Natural Resources Canada, CanmetENERGY, Ottawa, ON, Canada

This study presented the results of 3D unsteady CFD simulations to investigate the influence of adding a flat baffle plate at the entrance during the discharging operation on the flow behaviour, thermal stratification, and performance of a hot water storage tank installed in solar ...

Water Quality Model for Brewster Lake

Z. Aljobeh[1], G. Argueta[1]
[1]Valparaiso University, Valparaiso, IN, USA

A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the ... En savoir plus

Simulation of Ground Heat Exchanger for Cryogenic Applications

F. Bergeron[1], P. Pasquier[1]
[1]École Polytechnique de Montréal, Montréal, QC, Canada

Ground freezing techniques using liquid nitrogen are commonly used in order to increase the mechanical properties of the soils. This article presents a new ground heat exchanger using aluminum to increase the effective radius of the heat exchanger. Simulation results indicate that the ... En savoir plus
