Modelling of the Dynamical Fluorescent Micro-Thermal Imaging Experiment on the Heat Diffusion in the La5Ca9Cu24O41 Spin Ladder Compound

E. Khadikova[1], F. de Haan[1], P. H. M. van Loosdrecht[2]
[1]Zernike Institute for Advanced Materials, University of Groningen, Groningen, The Netherlands
[2]Department of Physics, University of Cologne, Köln, Germany

The dynamical fluorescent micro-thermal imaging (FMI) experiment has been used to investigate the phonon-magnon interaction in the 1D Heisenberg antiferromagnet La5Ca9Cu24O41. This material shows highly anisotropic heat conductivity due to the efficient magnetic heat transport along the ... Read More

3D-FEA of the Relationship between the Occiput and Sphenoid in the Osteopathic Paradigm

Y. Chiesa[1]
[1]Istituto Superiore di Osteopatia, Milan, Italy

The concept of cranial Primary Respiratory Mechanism (MRP) is used by osteopathic practitioners to explain the perceptual characteristics arising from the clinical palpation approach of the human skull. The theoretical apparatus and the same MRP existence is always element of ... Read More

Large and High Power Cylindrical Batteries - Analysis of the Battery Pack Temperature Distributions Using the COMSOL Multiphysics® and MATLAB® Simulation Softwares

O. Capron[1], A. Samba[1], N. Omar[1], H. Gualous[2], P. Van den Bossche[1], J. Van Mierlo[1]
[1]MOBI - Mobility, Logistics and Automotive Technology Research Centre, VUB - Vrije Universiteit Brussel, Brussels, Belgium
[2]Laboratoire LUSAC, Université de Caen Basse Normandie, Cherbourg-Octeville, France

The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is ... Read More

Simulation of a Micro-Scale Out-of-plane Compliant Mechanism

E. Rawashdeh[1], A. Arevalo[1], D. Castro[1], I. G. Foulds[2], N. Dechev[3]
[1]Computer, Electrical & Mathematical Sciences & Engineering Division (CEMSE), King Abdullah University of Science & Technology, Thuwal, Saudi Arabia
[2]School of Engineering, Okanagan Campus, The University of BC, Vancouver, BC, Canada
[3]University of Victoria, Victoria, BC, Canada

In this work we present the simulation of a micro-scale large displacement compliant mechanism called the Tsang suspension. It consists of a flat micro-plate anchored down by two springs on either side, that can rotate out-of-plane and maintain its vertical assembly by a simple single ... Read More

Support-Q Optimisation of a Trapped Mode Beam Resonator

T. H. Hanley[1], H. T. D. Grigg[1], B. J. Gallacher[1]
[1]Newcastle University, Newcastle-Upon-Tyne, UK

Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation ... Read More

Polyimide Thermal Micro Actuator

A. Arevalo[1], I. G. Foulds[2]
[1]Computer, Electrical and Mathematical Sciences and Engineering Division (CEMSE), King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2]School of Engineering, Okanagan Campus, The University of British Columbia, Vancouver, BC, Canada

Joule heating is simulated in COMSOL Multiphysics® software for the electro-thermal micro actuator. The aim is to choose the optimal design parameters to get the largest possible in-plane displacement. The comparison between the different possible configurations will reveal the optimal ...

Micromachined Silicon Integrating Cavities for Far-Infrared Bolometer Arrays

M. Audley[1], G. de Lange[1], G. Keizer[1], C. Bracken[2]
[1]SRON Netherlands Institute for Space Research, Groningen, The Netherlands
[2]National University of Ireland, Maynooth, Co. Kildare, Ireland

We are investigating gold-plated micromachined silicon integrating cavities for arrays of far infrared Transition Edge Sensor bolometers. We present the results of our simulations and show how we used COMSOL Multiphysics® software to optimize the geometry of the integrating cavity. We ... Read More

Mathematical Model of Vacuum Foam Drying

M. Sramek[1], J. Weiss[2], R. Kohlus[1]
[1]Department of Food Processing Engineering, Institute of Food Science and Biotechnology, Hohenheim University, Stuttgart, Germany
[2]Department of Meat Science and Food Physics, Institute of Food Science and Biotechnology, Hohenheim University, Stuttgart, Germany

The mathematical model is closely related to the development of a novel drying method for high viscous and sticky materials. The foamed state facilitates diffusive moisture transport and therefore accelerating the drying process. Moreover the dried porous material can be easily converted ... Read More

Numerical Analysis of the Self-Heating Behaviour of Coal Dust Accumulations

D.Wu[1], E. Van den Bulck[1]
[1]Katholieke Universiteit Leuven, Department of Mechanical Engineering, KU Leuven, Belgium

Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, ... Read More

Modelling of the Oxygen Consumption of Cells in the Cell Culturing Platform

A. Niazi[1]
[1]School of Mechanical Engineering, University of Birmingham, Birmingham, United Kingdom

A device for monitoring the oxygen consumption of cells has been developed, which consists of two parts; a cell culturing platform (CCP) and an oxygen sensing chip. The CCP possesses inlet and outlet pipes to direct the fluid under the test to the cell culturing chamber through the inlet ... Read More
