M4B, a Tool for the Analysis of THQM Behavior of Soils and Its Interaction with Building Foundations

J. Alonso [1], V. Navarro [1], M. Moya [1],
[1] Universidad de Castilla la Mancha, Ciudad Real, Spain

The Geoenvironmental Engineering Group of the University of Castilla-La Mancha is developing a computational tool, M4B, for describing the influence of environmental loads on the deformation behavior of soils and its interaction with building foundations. This tool comprises a set of ... En savoir plus

Antenna and Plasmonic Properties of Scanning Probe Tips at Optical and Terahertz Regimes

A. Haidary[1], P. Grütter[1], Y. Miyahara[1]
[1]Physics Department, McGill University, Montreal, QC, Canada

A wide variety of near-field optical phenomena such as apertureless near-field scanning microscopy (ANSM) at optical and terahertz (THz) regimes and surface enhanced Raman scattering relies on the electric field enhancement at the end of a sharp tip. Achieving and controlling this ... En savoir plus

Towards a Microscopic Model for Species Transport in Lithium-Sulphur Cells

Geraint Minton [1], Rajlakshmi Purkayastha [1], Laura O’Neill [1], Sylwia Walus [1], Mark Wild [1], Monica Marinescu [2], Teng Zhang [2], Gregory Offer [2],
[1] Oxis Energy Ltd, Abingdon, Oxfordshire, UK
[2] Mechanical Engineering Department, Imperial College, London, UK

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion ... En savoir plus

iCP Apps to Readily Solve Reactive Transport Simulations in COMSOL Multiphysics®

D. Negro [1], A. Sainz-Garcia [2], D. Sampietro [1], E. Coene [1], E. Abarca [1], A. Idiart [1], M. Laviña [1], O. Silva [1], J. Molinero [1],

[2] Amphos 21 Consulting S.L., Barcelona, Spain & Université Toulouse III, Toulouse, France

Reactive transport models (RTM) that couple physical and chemical processes are commonly used to solve a large variety of problems in the environmental industry. There are a series of codes designed to solve this kind of problems. However, their use requires typically much effort due to ... En savoir plus

Oxygen Based Diffusion Modeling of Oxidation Behaviour of Encapsulated Lipids

H. Teichmann [1], A. Linke [1], R. Kohlus [1],
[1] Process Engineering and Food Powders, University of Hohenheim, Stuttgart, BW, Germany

Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It ... En savoir plus

Finite-Element Evaluation of Thermal Response Tests Performed on U-Tube Borehole Heat Exchangers

E. Zanchini, and T. Terlizzese
[1]Dipartimento di Ingegneria Energetica, Nucleare e del Controllo Ambientale, Università di Bologna, Bologna, Italy

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by ... En savoir plus

Fully Coupled Thermo-Hydro-Mechanical Modeling by COMSOL Multiphysics, with Applications in Reservoir Geomechanical Characterization

T. Freeman[1], R. Chalaturnyk[1], and I. Bogdanov[2]
[1]University of Alberta, Edmonton, AB, Canada
[2]Centre Huile Lourde Ouvert et Expérimental (CHLOE), France

Because of the complex nature of geomaterials and presence of solid and fluid within a single system, it is crucial to consider all the physics involved within the geomaterial system. A fully coupled thermo-hydromechanical model is developed. The model consists of a three-phase flow ... En savoir plus

A. Briffaz [1], F. Coffigniez [1], C. Mestres [1], P. Bohuon [2],
[1] CIRAD, France
[2] Montpellier SupAgro, France

Cowpea seed is a pulse which is very rich in vital micronutrients but also in anti-nutritional factors such as α-galactosides (verbascose, stachyose and raffinose) that can cause digestive disorders after consumption. The objective of this work was to identify the transport and ... En savoir plus

Thermal Modeling in a Historical Building - Improving Thermal Comfort Through the Siting of a Passive Mass of Phase Change Material

D. Groulx[1], F. Herbinger[1], L. Desgrosseilliers[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

A model of an office room was created in the COMSOL Multiphysics® software to simulate heat transfer and study the impact of siting a mass of phase change material (PCM) in a room to increase thermal comfort. This study determined that incorporating the selected PCM, butyl stearate, in ... En savoir plus
