Power-to-heat-to-power systems are an interesting approach to deal with the intermittent power generation from renewable energy sources. However, storing heat requires large storage volume and associated heat losses decrease the system performance. High Temperature Heat Pump (HTHP) systems can operate during surplus power generation periods storing...
Article
The subject of the transport phenomena has a pivotal role in the performance of aqueous lithium bromide falling film absorbers. Although the thermodiffusion phenomenon appears inside the solution, very little is known about its influence on the mass transport. This study numerically analyses the influence of the thermal mass transfer mechanism on a...
Article
Hybrid Liquid Desiccant systems (HLDS) combine the liquid desiccant technology for dehumidification of air with conventional compression cycle technology for cooling. They are an alternative to conventional compression cooling systems, being more efficient and offering the possibility of independently control temperature and humidity. In this paper...
Article
Wettability has a key impact on the performance of LiBr-H2O horizontal-tube falling film absorbers working under typical operating conditions. Therefore, it is necessary to study the influence of the wettability properties on the film hydrodynamics and wetted area. This work analyses the influence of the contact angle (0° – 120°) on the transient f...
Conference Paper
The performance of a hybrid liquid desiccant prototype with non-adiabatic air-solution contactors is analyzed in this paper. In order to avoid corrosion all the components that are in direct contact with the liquid desiccant are made of plastic, especially the air-solution contactors that are made of polypropylene. The hybrid liquid desiccant syste...

Marine vessels are totally fuel dependent; thus, the fuel price is one of the main concerns of ship-owner companies. Vessels are totally isolated from the inland electrical grid when out of the ports. Energy demand on board is generated from internal combustion engines, related to the main propulsion, redundancy or auxiliary electricity generation....
Article
Predictive models for the design of falling film condensers and evaporators with water as refrigerant at vacuum operating conditions have been developed in the present work. The models developed in the EES (Engineering Equation Solver) environment will enable us to face the dimensioning and simulation of falling film evaporators and condensers usin...
Article
The comparative mechanical behavior of mold with magnetic molding using a cohesive granular material and lost foam process was compared. Finite element analysis calculates magnetic field and distribution of magnetic cohesion in steel shot moulds to determine optimum magnetizing equipment parameters. Internal friction measurements of steel shot and...
Article
The magnetic moulding process is based on the same moulding concept as the full mould process better known under the generic name of "Lost Foam"process. In the magnetic moulding process, the unbonded sand used in the "Lost Foam" process is replaced by steel shot, to which a magnetic field is applied during the pouring and solidification of the meta...
Article
Le procédé de moulage magnétique est basé sur le même concept de moulage que le procédé en moule plein, plus connu sous le nom générique de procédé "Lost Foom". Dans le cas du procédé de moulage magnétique, le sable non lié utilisé dans le procédé "Lost Foam" est substitué par de la grenaille d'acier à laquelle est appliqué un champ magnétique au c...
