Modeling RLSA CVD Processes in Ar+H2+C2H6 and Dopant Gas

J. Brcka[1], S. Gandhi[1], R. Joe[1]
[1]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

The plasma reactor with radial line slot antenna (RLSATM), a planar microwave plasma source, is used in etch and deposition technology, typically in reactive rich gaseous environments and for processes that are sensitive to plasma damage. Besides a strict uniformity control, the plasma ... Read More

Design of a Microreactor for Microwave Organic Synthesis through Microwave Heating Simulations

W. H. Lee[1], K. Jensen[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

We will present the issues of a microreactor setup designed for microwave organic synthesis and demonstrate how COMSOL Multiphysics® is used to understand the mechanism of microwave heating and improve the microreactor design. The RF Module was used for the electromagnetics and solid ... Read More

COMSOL Multiphysics® Simulation of Heat Generation from Hydrogen/Deuterium Loading of Nickel Alloy Nanoparticles

[1]University of Illinois at Urbana Champaign, Champaign, IL, USA

A key issue for the development of a LENR power unit involves the measurement and energy output of the reaction. Our team is currently studying a gas loaded nanoparticle-type cluster power unit [1] which pressurizes various nanoparticle alloys with either deuterium or hydrogen. The ... Read More

Studying Magnetohydrodynamic Effects in Liquid Metal Flow Under Transverse Magnetic Field Using COMSOL Multiphysics®

S. Sahu[1], R. Bhattacharyay[1], E. Rajendrakumar[1]
[1]Institute for Plasma Research, Bhat, Gandhinagar, India

Liquid metals are foreseen as a multipurpose coolant in fusion blanket systems. However, the strongly magnetic environment of the fusion reactor hinders the regular flow of the liquid metal. It interacts with transverse magnetic field and produces a Lorentz force opposing the flow, ... Read More

Numerical Modeling of Power Reactors' Fuel Bundles

R. Schmidt[1], T. Yousefi[2], B. Farahbaksh[2], M. Z. Saghir[2]
[1]University of Louisiana at Lafayette, Lafayette, LA, USA
[2]Ryerson University, Toronto, ON, Canada

Fuel bundles in the CANDU (CANada Deuterium Uranium) reactor are designed for heating a pressurized coolant (heavy water) to generate electricity. The designs for the fuel bundles differ based on the number of heating elements. The flow of heavy water over the elements and inside the ... Read More

Numerical Prototyping of Locally Heated Digital Microfluidic Devices

C. Ozen [1], G. Sathyanarayanan [1], S. Cito [2], T. Sikanen [1],
[1] Faculty of Pharmacy, Drug Research Programme, University of Helsinki, Helsinki, Finland
[2] Department of Mechanical Engineering, Rovira i Virgili University, Tarragona, Spain

An alternative approach to integration of a local heat source with the digital microfluidic (DMF) platform by attaching inkjet-printed silver microheaters to the bottom plate was recently introduced (Sathyanarayanan et al., MNE 2017). This approach allows more degrees of freedom to the ... Read More
