[1] Center for Sustainable Future Technologies, Istituto Italiano di Tecnologia, Torino, Italy
[2] Dipartimento di Scienza Applicata e Tecnologia, Politecnico di Torino, Alessandria, Italy

The search for energy saving is nowadays mandatory because of the constant growth of CO2 emissions caused by an inefficient energy management. Thermal Energy Storage (TES) has an important role in designing of energy efficient systems, including solar energy storage (daily or seasonal) ... En savoir plus

Optimal Design of Flow Distributors for Detecting Blocked Microreactors

Osamu TONOMURA[1]
[1]Kyoto University, Kyoto, Kyoto, Japan

When the production capacity of micro chemical plants is increased by numbering-up approach, it is important to realize the uniform flow distribution among the parallelized microreactors. In addition, a blocked microreactor needs to be identified as early as possible to achieve the ... En savoir plus

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

Experimental and Modeling Study of the Filtering Capacity of Green Wall Species

T. Ysebaert [1], S. Denys [1], G. Walpot [1],
[1] University of Antwerp, Belgium

Air pollution caused by particulate matter (PM) is one of the most severe issues in urban environments. Urban green infrastructure (UGI), in particular green walls, have been proven to be capable of capturing PM via deposition on leaves. This phenomenon was assessed by numerical ... En savoir plus

Flow Modeling in Long Surface Patterned Micromixers Using Division in Multiple Geometrical Subunits

Optimization of mixing in microfluidic devices is a popular application of computational fluid dynamics software packages, such as COMSOL Multiphysics, with an increasing number of studies being published on the topic. On one hand, the laminar nature of the flow and lack of turbulence in ... 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 ...

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

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
