Convective Heat and Moisture Transfer Modelling in Porous Insulation for Large Thermal Storage

Alice Tosatto¹, Michele Bianchi Janetti¹, Fabian Ochs¹
¹Unit of Energy Efficient Building, Universität Innsbruck, Innsbruck, Austria

In view of an energy system based on fluctuating renewable sources, the use of thermal energy storage (TES) systems plays a crucial role. In particular, large-scale underground water-based TES represent a promising solution as demonstrated by a number of cases currently being established ... En savoir plus

Simulation/Validation of Pollutant Transport in Rivers Using COMSOL Multiphysics®

Larry J. Matel¹
¹Green Streets Infrastructure LLC, USA

Our atmosphere, land, and water are being continuously besieged by pollutants caused by such events as heavy metals leaching from mine tailing ponds, chemical spills from railroad and truck tanker accidents, and petroleum pipeline failures, to name just a few. These environmental ... En savoir plus

Development of a Single Cell Trapping Microfluidic Device

L. Weng [1], F. Ellett [1], J. F. Edd [1], M. Toner [1,2],
[1] Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA
[2] Shriners Hospital for Children, Boston, MA, USA

Array-based technologies are important for many applications in drug discovery, microbiology and cell biology. A large-scale array of single cells allows high-throughput monitoring of behaviors of individual cells in parallel, avoiding the lack of cell specificity inherent to bulk ... En savoir plus

Particle Velocimetry Data From COMSOL Model of Micro-channels

P. Mahanti, M. Keebaugh, N. Weiss, P. Jones, M.A. Hayes, and T. Taylor
Arizona State University, Tempe, AZ, USA

Particle velocimetry using image analysis is an effective non-intrusive method used for fluid velocity field estimation in micro-channels. We use COMSOL with MATLAB to generate velocity fields for micro-channel designs and then calculate changes in particle position for given imaging ... En savoir plus

Modeling of Acoustically Induced Rapid Mixing Processes in Microchannels Using Acoustic Streaming

S. Wiesinger¹, W. Wiedemair¹
¹OST - University of Applied Sciences Eastern Switzerland, Buchs SG, St. Gallen, Switzerland

Technical advancements in miniaturization in the last decades have, among others, brought forth the technology of so called “Lab-on-a-Chip” (LOC) systems. These systems provide the possibility to automate and accelerate certain laboratory processes, e.g., biomedical diagnostics, on the ... En savoir plus

Application of an Electromagnetic Analogy in the Simulation of a Problem in Classical Hydrodynamics

J. Russell[1]
[1]Florida Institute of Technology, USA

The present author’s specialty is Aerodynamics, a field in which problems in unbounded fluid domains are common. The COMSOL Multiphysics® simulation software's support of Infinite Elements is attractive as a tool for addressing such problems. Be that as it may, neither the COMSOL ... En savoir plus

Modelling Thermal Capillary Effects and Flow in the Molten Pool During Selective Laser Melting

Habimana Jean Willy [1],
[1] National University of Singapore, Singapore

Laser additive manufacturing has become an interesting field of engineering which is revolutionizing industrial processes. Selective Laser melting (SLM) is a widely used additive manufacturing technique for 3D printing of metal structures. This process has a particular complexity in ... En savoir plus

Development of a Laser Cladding Process Model

F. Wirth [1], K. Wegener [1],
[1] IWF, ETH Zürich, Switzerland

Additive manufacturing is attracting more and more interest. Laser Cladding is one of these additive manufacturing processes. For this a quasi-stationary physical based 3D process model is presented, which has been developed taking into account heat transfer, melt pool fluid flow ... En savoir plus

3D Acoustic Streaming Field in High-Intensity Discharge Lamps

B. Baumann[1], J. Schwieger[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low ... En savoir plus

Experimental and Numerical Fluid Flows Study on a X-Millichannel
