Heat and mass transfer in falling films technology applied to the generator and the rectifier of an ammonia-water absorption refrigeration cycleTransfert de chaleur et de masse dans la technologie des films tombants appliquée au générateur et au rectificateur d'un cycle frigorifique à absorption d'ammoniac-eau
(2022-03-01)
Powering ammonia-water absorption refrigeration cycles with solar energy demands an operating temperature above 170 ∘C for the proper generator operation when conventional flooded generator technologies are used. However, ...
Linear stability of electron-flow hydrodynamics in ungated semiconductors.
(2009)
Semiconductors play an important role in modern electronic technology. They are present in most sensing and transduction applifations, satisfying requirements such as compactnes, tuanbility and portability. It is known ...

A causal flow approach for the evaluation of global climate models
(2020)
© 2020 Royal Meteorological Society Global climate models (GCMs) are generally used to forecast weather, understand the present climate, and project climate change. Their reliability usually rests on their capability to ...
Natural modes of the two-fluid model of two-phase flow
(American Institute of Physics, 2021-03)
A physically based method to derive well-posed instances of the two-fluid momentum transport equations from first principles is presented. The basic tools used in this endeavor are the variational principles of field theory, ...
Implementation of a thermo energetic model of an electric arc furnace using static approach.
In this work two mathematical models that describe the performance of an Electric Arc Furnace (EAF) are presented: Mass and energy balances and the heat rate transfer model. The mass and energy balances use real data taken ...
Effect of geometry on flow structure and pressure drop in pneumatic conveying of solids along horizontal ducts
(CSIR-NIScPR, 2011-02)
This study presents further developments in Euler/Lagrange approach to calculate confined particle-laden flows in pneumatic conveying lines. Special emphasis is placed on influence of particle-wall collisions and wall ...
Mass-transfer study and copper ions removal using a modified hydrocyclone as electrochemical reactor
(Electrochemical Society, 2017-01)
Mass-transfer coefficients between an electrolyte solution and the wall of a hydrocyclone were experimentally determined by using the electrochemical technique. The local mass-transfer coefficients were measured as a ...
Approximation and interpolation of divergence free flows.
(Udelar.FI., 1999)
In many applications like meteorology, atmospheric pollution studies, eolic energy prospection, estimation of instantaneous velocity fields etc., one faces the problem of estimating a velocity field that is assumed to be ...
