3D Simulation Of Fatty Acid Methyl Ester Production In A Packed Membrane Reactor

B. Sajjadi [1]
[1] University of Malaya, Malaysia

The current work is aimed to simulate the production of high quality fatty acid methyl ester (biodiesel) production from palm oil in a micro porous ceramic membrane reactor. The TiO2/Al2O3 ceramic membrane was used as the separator and catalytic bed. It was packed with potassium hydroxide catalyst supported on palm shell activated carbon. The investigation of component distribution within the ...

[2] GE Global Research, Bangalore, Karnataka, India

The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in the flame. From earlier experiments it was established that the electrical power required to do so is very less ...

Thin Membrane Modelling for the Electrical Stimulation of Auditory Nerve

A. Grünbaum[1], S. Petersen[1], H.W. Pau[2], and U. van Rienen[1]

[1]IEF funded by DFG Research Training Group 1505/1 Welisa, University of Rostock, Rostock, Germany
[2]Otolaryngology “Otto Körner”, University of Rostock, Rostock, Germany

Modeling of 2-5 μm thin membranes into a cochlea with a width of 2 cm is computationally. The paper is focused on two approximative methods used to overcome this problem and in addition a simple model challenging of a plate capacitor with a thin membrane of different thickness in-between is presented. The results of simulations with both thin layer approximation methods are compared with ...

Fluid Flow Simulation of Preconcentration Membranes Using Finite Elements Tools

R. Inglés[1], J. Pallares[2], J.L. Ramirez[1], and E. Llobet[1]

[1]Dept. of Electronic, Electrical and Automatic Control Engineering, Universitat Rovira i Virgili, Tarragona, Spain
[2]Department of Mechanical Engineering School of Chemical
Engineering Universitat Rovira i Virgili, Tarragona, Spain

We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. So, we are wasting most part of our fluid and we need a lot of time to have a good concentrator factor. We ...

Optimization of a Thermal Actuator for Low Power/Low Cost Applications

R. Zúñiga-Quesada[1], M. Vílchez-Monge[1], P. Vega-Castillo[1]
[1]Instituto Tecnológico de Costa Rica, Cartago, Costa Rica

This work describes the study of a thermal actuator and modifications to the materials employed in order to decrease power consumption and implementation costs. For this study, we worked on improving the thermal actuator described in the work of T. Ebefors. The criteria for choosing the new materials were lower power consumption, commercial availability, and ease processing. The thermal actuator ...

Stochastic Modeling of Biological Systems – Ranking the Model Parameters of the Human Vocal Folds

D. Cook[1]
[1]New York University, New York, USA

Computational models of biological systems are becoming more and more common in medical research areas. Evidence of this can be found by examining the number of articles containing the term “finite element” in the expansive National Institutes of Health (NIH) digital research archive PubMed. Numerical modeling of biological systems allows the execution of “computational ...

Computational Modeling of Magnetorheological Elastomers Using Soft and Hard Magnetic Particles

J. Biggs[1], P. VonLockette[1], and S. Lofland[1]
[1]Rowan University, Glassboro, New Jersey

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...
