Fluid Motion Between Rotating Concentric Cylinders Using COMSOL Multiphysics® Software

P. L. Mills [1], K. Barman [1], S. Mothupally [1], A. Sonejee [1],
[1] Texas A&M University - Kingsville, Kingsville, TX, USA

Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, ... En Savoir Plus

Modeling Darcian and Non-Darcian Porous Media with COMSOL Multiphysics® Software

A. Kumar [1], S. Pramanik [2], M. Mishra [1],
[1] Indian Institute of Technology Ropar, Rupnagar, Punjab, India
[2] Indian Institute of Technology Ropar, Rupnagar, Punjab, India; Nordita, SE-10691, Stockholm, Sweden

Darcian and non-Darcian porous media are characterized by the porosity of medium. To capture miscible viscous fingering in both types of porous media, a new model built with COMSOL® software is presented by coupling of two different physics interfaces (hydrodynamics and transport of ...

A lithium-ion battery comprises of two intercalating electrodes separated by a membrane, sandwiched between aluminum and copper current collecting plates. The battery performance depends upon several parameters and its operating conditions. In this work we developed a model for a lithium ... En Savoir Plus

Modeling of Supercapacitor

G. Madabattula[1], S. K. Gupta[1]
[1]Department of Chemical Engineering, Indian Institute of Science, Bangalore, Karnataka, India

Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing ... En Savoir Plus
