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

A Multiphase Model to Analyze Transport Phenomena In Convective Drying

S. Curcio, and M. Aversa
Department of Engineering Modelling, University of Calabria, Rende, Italy

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around ... Read More

Using CFD to Predict the Performance of Innovative Wind Power Generators

D. Allaei[1]
[1]Sheer Wind Inc., Chaska, MN, USA

INVELOX is an innovative wind power generation system as shown in Figure 1. It is comprised of a wind capturing system that accelerates and delivers high kinetic energy wind to a power conversion system placed in the Venturi section of the INVELOX. The objective of this project is to ... Read More

Direct Numerical Simulation of Time Evolution of Vortex Ring

M. Hashiguchi [1],
[1] Keisoku Engineering System Co., Ltd., Chiyoda-ku, Tokyo, Japan

Vortex ring can be useful to generate thrust force for e.g., jellyfish, but its mechanism has not been clarified. In this field, it seems that numerical simulation has an important role of understanding the propulsion mechanism of creature. A vortex ring in a tube, refered to confined ... Read More

Efficiency of a Vertical Axis Wind Turbine (VAWT) with Airfoil Pitch Control

J. Ma [1], C. Koutsougeras [2], H. Luo [2],
[1] Sam Houston State University, Huntsville, TX, USA
[2] Southeastern Louisiana University, Hammond, LA, USA

In this work, the CFD Module of COMSOL Multiphysics® software is used to study the efficiency of a Vertical Axis Wind Turbine (VAWT) with independently pivoting airfoils so that wind attack angles of these airfoils are adjustable. The work demonstrates how the efficiency of the VAWT is ... Read More

[1]The University of Birmingham, School of Chemical Engineering, Edgbaston, Birmingham, United Kingdom

Worldwide attention in the computational modeling and simulation of the human intestine is increasing in order to help understand its complex behavior and improve health. Computational fluid dynamics is an essential tool to understand the mechanics and transport phenomena of the human ... Read More

Hemodynamic Simulations of Implanted Multilayer Flow Modulator

A.B. Boubker[1], A. Restante[1]
[1]CARDIATIS, Isnes, Belgium

Ruptured aortic aneurysm is one of the commonest cause of mortality in developed countries. To avoid it interventional repair is an effective treatment. In the recent years the development of new therapies, such as stent implantations, allows to perform this treatment more and more ... Read More

Simulation of PCM Melting Process in a Rectangular Enclosure Differentially Heated

G. Petrone[1], G. Cammarata[1]
[1]Department of Industrial Engineering, University of Catania, Catania, Italy

This study deals with a numerical investigation of the melting process of a PCM in a rectangular enclosure differentially heated. COMSOL Multiphysics is used in order to numerically solve Navier-Stokes and energy equations in the considered system. Adopting an enthalpy formulation, one ... Read More

The Gas Electron Multiplier (GEM) technology has been proven to tolerate rate larger than 50 MHz/cm2 without noticeable aging and to provide the sub millimeter resolution on working chambers up to 45x45 cm2. A new GEM based tracker is under development for the Hall A upgrade at ... Read More

Thermal Performance of the New Bioclimatic Hall of the Historical Hospital in Florence

C. Balocco, and E. Marmonti
Dipartimento di Energetica “Sergio Stecco”
Università degli Studi di Firenze
Firenze, Italy

The main aim of the present work is the study of the thermal and energy performances of the new hall of the Old St.Maria Nuova Hospital in the center of Florence (Italy). Transient simulations were carried out of the 3D model of the hall to analyse the air flow patterns, distribution and ... Read More
