Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... Mehr lesen

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. ... Mehr lesen
