[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 ... Per saperne di più

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 ... Per saperne di più
