Simulating the Electrical Double Layer Capacitance

G. Zhang
Clemson University, Clemson, SC, USA

When a solid surface makes contact with a liquid medium, an electrical double layer (EDL) structure forms spontaneously through thermodynamic interaction between electrons and ions. In this study, we developed a computational model using commercial finite element analysis package COMSOL ... En savoir plus

Numerical Analysis of Different Magnet Shapes on Heat Transfer Application using Ferrofluid

H. Garg [1], A. S. Kharola [1], V. Karar [1],
[1] Central Scientific Instruments Organization, Chandigarh, India

A magnetic colloid, also known as a ferrofluid, is a colloidal suspension of single-domain magnetic particles with typical dimensions of about 10nm, dispersed in a liquid carrier. Since the 1960, when these materials were initially synthesized, their technological applications are ... En savoir plus
