Analysis of Multiphysics Problems Related to Energy Piles

E. Evgin[1], J.A.I. Sedano [1], Z. Fu[1]
[1]University of Ottawa, Ottawa, ON, Canada

Energy piles transfer the mechanical loads from buildings to the ground and serve as heat exchangers. Temperature changes in the ground influence its moisture content. This paper examines the effect of soil moisture content on the shaft resistance of a pile. Tests were carried out in ... Read More

Numerical Analysis and Experimental Verification of a Fire Resistant Overpack for Nuclear Waste

P. Geraldini [1], A. Lorenzo [1],
[1] Sogin S. p. A., Rome, Italy

Confinement systems for nuclear waste are usually designed to perform and ensure safety in view of all the assumed design basis events, including fires. Considering waste typology and radioactivity, the goal of the confinement system design is to protect the content of the steel drums ... Read More

Wind Flow Modeling of Area Surrounding the Case Western Reserve University Wind Turbine

M. Fernandes[1], D. Matthiesen[1]
[1]Case Western Reserve University, Cleveland, OH, USA

The CWRU Turbine is a research turbine located in a urban campus in Cleveland, Ohio. This location may create turbulence, resulting in a possible loss in energy generation. This research attempts to answers the question of whether the wind flow is affected by the buildings or not. The ... Read More

Modelling of a Wool Hydrolysis Reactor

M. Giansetti[1], A. Pezzin[1], S. Sicardi[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes ... Read More

Calibration of Ultrasonic Testing for Faults Detection in Stone Masonry

M. Usai[1], S. Carcangiu[1], G. Concu[2]
[1]Department of Electrical and Electronic Engineering, University of Cagliari, Cagliari, Italy
[2]Department of Civil Engineering, Environmental and Architecture, University of Cagliari, Cagliari, Italy

In the field of assessment methodologies, particular importance is given to Non-Destructive Testing Techniques, which aspire to achieve the highest number of information about materials and structures without altering their condition. Ultrasonic Testing exploits the transmission and ... Read More

Mechanical Strength Simulation of Concrete Samples Using COMSOL Multiphysics® Software with 3D Mesh Generated by Industrial Tomography System

W. C. Godoi[1], D. A. Ussuna[2], S. J. Ribeiro[2], K. de-Geus[3], V. Swinka-Filho[2], F. C. de-Andrade[3], K. F. Portella[2], B. L. Medeiros[2], R. C. R. Santos[4]

[4]Universidade Federal do Paraná, Curitiba, PR, Brazil

Analysis of concrete structures is usually carried out by destructive methods. The internal volume flaws directly influence concrete properties. Such inclusions are empty or even resulting from the manufacturing process or degradation by percolation leaching dissolution and chemical ... Read More

Modeling the Performance of Energy Recovery Ventilators

N. Lemcoff[1], R. Pastor[2], and E. Miravete[1]
[1]Rensselaer Polytechnic Institute, Hartford, CT
[2]General Dynamics Electric Boat, Groton, CT

The objective of this study is to numerically evaluate the effectiveness of an energy recovery ventilator (ERV) during the summer and winter seasons. The energy recovery ventilator allows heat and mass transfer between two air streams separated by a membrane. The effects of varying the ... Read More

Structural Analysis of the Advanced Divertor eXperiment's Proposed Vacuum Vessel

J. Doody [1], R. Vieira [1], B. LaBombard [1], R. Leccacorvi [1], J. Irby [1], R. Granetz [1]
[1] Plasma Science and Fusion Center - Massachusetts Institute of Technology, Cambridge, MA, USA

The goal of a tokamak is to use high magnetic fields to contain plasma and produce nuclear fusion that can be used for power generation. MIT’s Plasma Science Fusion Center (PSFC) and collaborators are proposing a machine, the Advanced Divertor eXperiment (ADX) to test new technology for ... Read More

A Computational Study of the Reynolds Piped flow Experiment

Sanidhya Painuli[1], Jayasankar Variyar[1]
[1]Vellore Institute Of Technology, School of Mechanical and Building Sciences, Vandalur Kelambakkam Road, Chennai, India

The study of interaction of fluid with matter assumes great significance for most engineering applications. The flow can be either turbulent or laminar, and different types of interactions arise out of these flow. In the introductory undergraduate course of fluid mechanics, a typical ... Read More

Design of MEMS Based 4-Bit Shift Register
