Failure Stress Analysis of Fiber Reinforced of Composite Laminates under Uniaxial/Biaxial Loading

Z. Hasan[1], F. Darwish[2], and S. Al-Absi[2]
[1]Texas A&M University, College Station, TX, USA
[2]Jordan University of Science and Technology, Irbid, Jordan

The main objective of the present work is to perform stress analysis on composite laminates under unaxial/biaxial loading to serve as a preliminary data for test verification. A detailed calculation based on the Classical Lamination Theory was performed for a laminate. The material used ... En savoir plus

Energy Harvesting from Variation in Blood Pressure through Deformation of Arterial Wall using Electro-magneto-hydrodynamics

A. Pfenniger[1], V.M. Koch[2], A. Stahel[2], and R. Vogel[1]
[1]ARTORG Cardiovascular Engineering, University of Bern, Bern, Switzerland
[2]Bern University of Applied Sciences, Engineering and Information Technology, Biel, Switzerland

The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is ... En savoir plus

Effective Thermal Conductivity of Composite: Numerical and Experimental Study

M. Karkri
Université Paris-Est, CERTES, Créteil Cedex, France

In this paper, thermal properties of composites are investigated numerically and experimentally. In the numerical study, finite-elements method in COMSOL is used to modelize heat transfer and to calculate the Effective Thermal Conductivity (ETC) of the composite for three elementary ...

Modeling of Wettability Alteration during Spontaneous Imbibition of Mutually Soluble Solvents in Mixed Wet Fractured Reservoirs

M. Chahardowli[1], H. Bruining[1]
[1]Delft University of Technology, Delft, The Netherlands

Mutually-soluble solvents can enhance oil recovery both in completely and partially water wet fractured reservoirs. When a strongly or partially water-wet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production ... En savoir plus

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 ... En savoir plus

Mixers and Pumps for Microfluidic Systems, based on Conducting Polymer Oxidation Wave

K. Kannappan, G. Bogle, J. Travas-Sejdic, and D.E. Williams
University of Auckland, Auckland, New Zealand

Electrochemically-active conducting polymers (ECP) swell or shrink in response to ion and solvent incorporation or ejection as a result of electrochemical reaction of the polymer. When anodic potential is applied to an electrode attached to one end of ECP strip, the oxidation process ... En savoir plus
