We present a mechanical model a growing spherical shell suitable for predicting the evolution of a Saccular Cerebral Artery Aneurysms (SCAA). It relies basically on the Kröner-Lee decomposition, used to describe the interplay between the current and the relaxed configuration of body elements. Rupture or stabilization of a SCAA are the end effect of a number of biological mechanisms, still poorly ...

An Extension of Lauwerier’s Solution for Heat Flow in Saturated Porous Media

[1]Technical University of Delft, Delft, The Netherlands
[2]Deltares and TU-Delft, Delft, The Netherlands

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...

Evaluation of COMSOL as a Tool for Pinpointing Moisture Entering Locations From Inside Surface Moisture

J. van Schijndel
Eindhoven University of Technology, Eindhoven, Netherlands

The location and nature of the moisture leakages are sometimes difficult to detect. Moreover, the relation between observed inside surface moisture patterns and where the moisture enters the construction is often not clear. The objective of this paper is to investigate inverse modeling techniques as a tool for the detection of moisture leakage locations in building constructions from inside ...

Design of Novel Recirculation System for Slow Reacting Assays in Microfluidic Domain

N.N. Sharma, and A. Tekawade
Mechanical Engineering Group, Birla Institute of Technology & Science, Pilani, Rajasthan, India

A simple design for a microfluidic flow system for use in mixing or reacting assays with limited sample availability has been proposed and analyzed using COMSOL\'s multiphysics simulation package. The design is based on differential electroosmotic flow concept which has facilitated a number of interesting flow phenomena in micro-domains. For an average potential drop of about 86 kV/m in the ...

Simulation Of Soil Remediation Polluted By Hydrocarbons Using A Non-Thermal Atmospheric Plasma

J. Rojo, S. Ognier, and S. Cavadias
Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, University Pierre et Marie Curie, Paris, France

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent treatment of the generated gases or liquids. Of all the decontamination methods, bioremediation appears to be the ...

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes - new

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually seeing and acoustically listening for defects has been problematic for an industry facing nearly a trillion ...

Modeling Alpha-Galactosides Behavior during Cowpea Soaking-Cooking for Nutritional Optimization - new

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 reactivity properties of α-galactosides as a function of soaking-cooking process conditions (time, temperature, etc.) ...

Mazar’s Damage Model for Masonry Structures: a Case Study on an Italian Church - new

M. Mori [1], A. De Falco [1], G. Sevieri [2],
[1] Università di Pisa, Italy
[2] Università di Firenze, Italy

Structural safety assessment of cultural heritage masonry structures plays an important role in safeguarding their integrity and conservation. In this regard, masonry modeling is one of the most challenging tasks, since an accurate reproduction of its mechanical behavior is necessary to assess the overall bearing capacity of the structures. In Finite Elements Methods, a realistic constitutive ...

Numerical Optimization of Active Heat Sinks Considering Restrictions of Selective Laser Melting - new

[1] Fraunhofer Institution for Additive Production Technologies IAPT, Hamburg, Germany

Parametric and topology optimization approaches are widely used techniques for performance improvement of components in terms of various objectives. Especially topology optimization often leads to complex geometries that are difficult or impossible to produce by conventional manufacturing processes. Due to its great freedom in shape and structure design, additive manufacturing methods like ...
