Resumen
A steady-state model is presented of the operation of a water-ammonia absorption system for production of scale ice. The model involves relations of thermodynamics, heat transfer, and fluid mechanics, and uses simplifying assumptions for the internal mass transfer processes, leading to a non-linear system with more than 100 unknowns and equations, that are reduced to a dimension-10 Newton-Raphson problem by means of the Substitution-Newton-Raphson approach. The model was validated against experimental data with good agreement. Copyright © 2006 by ABCM. 28 4 413 421 Churchill, S.N., Friction factor equation span all fluid flow regimes (1977) Chem.
