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 ... Read More

Surface to Surface Radiation Benchmarks

J. v. Schijndel [1], R. v. Eck [1], M. Klep [1],
[1] Eindhoven University of Technology, Eindhoven, Netherlands

The paper presents a student guide on how to implement surface to surface radiation within COMSOL Multiphysics® software for case studies found within the built environment. We included four benchmarks: (1) Radiation in a triangular cavity with infinite length; (2) Radiation between two ... Read More

Process Modeling and Optimization of Design Parameters in a Falling Film Plate and Frame Evaporator

A. Donaldson [1], A. Thimmaiah [2],
[1] Dalhousie University, Halifax, Nova Scotia, Canada
[2] National Institute of Technology Karnataka, Mangalore, Karnataka, India.

COMSOL Multiphysics® software is used to explore the impact of distributor width on the film thickness, and the resulting sensitivity of overall thermal efficiency in a plate and frame triple-effect evaporator. A stable film is crucial to maintain a minimum wetting rate, to circumvent ... Read More

The Use of Finite Element Analysis in the Design of Oil-Water Separators

M. E. Wanas [1], Y. M. Elshazly [1], D. A. ElGayar [1],
[1] Chemical Engineering Department, Faculty of Engineering, University of Alexandria, Alexandria, Egypt

Oil-water separators play an important role in several industries as well as in waste water treatment. However, no basic principles have been set to guarantee the designed separators would work according to the desired efficiency due to the effect various factors. Both time and money ... Read More
