Analysis on Reaction Mechanism and Kinetics of CVD using COMSOL Multiphysics®

Yudai SUZUKI[1]

[1]The University of Tokyo, Tokyo, Japan

Chemical vapor deposition (CVD) is widely used in various fields including the fabrication of electronic devices due to its uniform film formation capability on the large-scale wafers and the minute 3D structures. In CVD, precursors (metal compounds) are commonly reacted in gas-phase as ... En savoir plus

Multiphysics Analysis of a Photobioreactor

[2] ArcelorMittal Eisenhüttenstadt GmbH, Eisenhüttenstadt, BB, Germany
[3] AG der Dillinger Hüttenwerke, Dillingen, SL, Germany

The blast furnace is a counter flow reactor to produce pig iron. The molten pig iron and byproduct slag are accumulated at the hearth of the furnace, from where they are tapped regularly. The blast furnace has to stay continuously in operation for many years to prevent solidification of ... En savoir plus

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to ...

Improvements in the Modeling of the Self-ignition of Tetrafluoroethylene

M. Beckmann-Kluge, F. Ferrero, V. Schröder, A. Acikalin, and J. Steinbach
Federal Institute for Materials Research and Testing, Technical University, Berlin, Germany

Tetrafluoroethylene (TFE) is a gas widely employed in industry, which can under specific circumstances experience an exothermic dimerization to octafluorocyclobutane. If the heat generated by this reaction cannot be dissipated to the surroundings, the temperature inside the reactor will ... En savoir plus

Estimation of Tungsten Melt-Zone Size During Transient Heat Loads

Y. Patil[1], S. S. Khirwadkar[1], S. Belsare[1]
[1]Institute for Plasma Research, Gandhinagar, Ahmedabad, India

Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. ...
