A Heat Transfer Simulation for Heat Management in the Design of a New ReactorSTM

Elahe Motaee¹, Dr. Irene M.N. Groot¹
¹Leiden University

With the ReactorSTM the relationship between surface structure and catalyst activity under industrially relevant conditions can be investigated. It enables atomic-scale observations of model catalysts under conditions approaching those used by the chemical industry. It consists of a ... En savoir plus

3D Acoustic-Structure Interaction of Ultrasound in Fluids for the Manufacture of Graded Materials

J. Holt [1], C. Torres-Sanchez [1], P. Conway [1], M. G. Garcia-Romero [1],
[1] The Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, Leicestershire, UK

Functionally graded materials (FGM) are those that contain chemical, phase or structural gradients. Whilst the design of functionally graded structures is well researched in areas such as shape optimisation and topology optimization, their manufacture is still in development. One ...

Study of Rotation of Ellipsoidal Particles in Combined Simple Shear Flow and Magnetic Fields

C. Wang [1], J. Zhang [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study creates a 2D fluid-structure interaction (FSI) model to study the effect of magnetic field and particle aspect ratio on the period of rotation and symmetry of ellipsoidal paramagnetic particles. The results show that the magnetic field strength has a significant effect on the ... En savoir plus

Efficient Geothermal Cooling in Harsh Environments: A Combined Experimental and Modelling Approach

Mohammed Al-Azba¹, Ahmed Abotaleb²
¹Qatar Environment and Energy Research Institute, HBKU, Qatar Foundation, Doha, Qatar
²ICube Laboratory, Université de Strasbourg-CNRS, 67000 Strasbourg, France

In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... En savoir plus

Chaining Dynamics of a Pair of Ellipsoidal Micro-Particles Under a Uniform Magnetic Field

J. Zhang[1], C. Wang[1]
[1]Missouri Univ of Sci and Tech, USA

Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... En savoir plus

Parametric Investigation of the Common Geometry Shapes for Added Mass Calculation

J. H. Lee [1], A. Koushesh [1],
[1] American University of Sharjah, United Arab Emirates

This work is aimed to demonstrate how variation of geometries' parameters would affect the fluid loading effect in water using COMSOL Multiphysics and compared with analytical data. When a structure is placed in water, the interaction between the water and the structure plays an ... En savoir plus

Simulation of a Novel Induced-Charge Electrokinetic Actuation Mechanism for a Diaphragm Micropump

A. Eden[1], F. Lorestani[1], S. Mackenzie[1], S. Minne[1], D. Huber[1], C. Meinhart[1], S. Pennathur[1]
[1]University of California, Santa Barbara, USA

From microelectronics cooling to biological analysis and wearable therapeutic infusion systems, micropumps are steadily becoming a valuable and ubiquitous tool for fluid transport and thermal management. Hence, the development of novel actuation mechanisms that allow for precise ... En savoir plus

Simulation of CMOS Compatible Sensor Structures for Dielectrophoretic Biomolecule Immobilization

H. Matbaechi Ettehad [1], S. Guha [1], C. Wenger [1],
[1] IHP, Frankfurt (Oder), Brandenburg, Germany

The aim of this paper is to optimize with COMSOL Multiphysics® simulation, the design geometry of a near field biosensor which could be used for dielectrophoretic (DEP) immobilization and simultaneous sensing of biomolecules of the order of nanometers to micrometers. COMSOL Multiphysics® ... En savoir plus

Influence of the Complexing Agent on the Throwing Power during Silver Electroplating

C. Baumer¹, A. Bund¹
¹Technische Universität Ilmenau, Ilmenau, Germany

The throwing power is an important criterion for the industrial use of an electrolyte in electroplating applications. Using the Electrodeposition Module and COMSOL Multiphyiscs® it is possible to simulate the thickness distribution for various electroplating geometries. For a realistic ... En savoir plus

Simulation of an Under Lake Infrastructure for Capture and Storage of Solar Energy (ULISSE)

Rozsnyo Roland¹, William van Sprolant², Daniel Bello-Mendes¹
¹hepia, HES-SO, Geneva, Switzerland
²CvS Énergies, sàrl, Geneva, Switzerland

The transition from fossil fuels to renewable energies requires finding new sources of energy. It turns out that the hydrothermal potential of the lakes would cover a significant part of these renewable energy needs. The existing Thermal Lacustrine Networks (TLNs) are efficient in summer ...
