A case study for decentralized heat storage solutions in the agroindustry secto...
Simão, Carlos; Murta-Pina, João; Oliveira, João Pedro; Coelho, Luis Manuel Rodrigues; Pássaro, João; Ferreira, Diogo; Reboredo, Fernando; Jorge, TiagoThe development of thermal energy storage solutions (TES) in agroindustry allows reduc- tion of production costs and improvement of operation sustainability. Such solutions require high storage capacity and the ability to adapt to existing equipment. The use of phase change materials (PCMs), which are able to store thermal energy as latent heat, creates new opportunities for heat storage solutions (LHS, latent ...
Effect of fins and nanoparticles in the discharge performance of PCM thermal st...
Pássaro, João; Rebola, A.; Coelho, Luis Manuel Rodrigues; Conde, J.; Evangelakis, J.A.; Prouskas, C.; Papageorgiou, D. G.; Zisopoulou, A.This work studies the heat exchange process of a latent heat thermal energy storage (LHTES) system equipped with a compact finned tubes heat exchanger (HE) as this is one of the most important aspects of the storage system, the capacity for effectively delivering its stored energy. This work fills in a literature gap for 3D, transient heat transport fluid (HTF) flow models concerning storage systems with phase ...
Numeric study of geothermal borehole heat exchanger enhancement via phase chang...
Pássaro, João; Rebola, A.; Coelho, Luis Manuel Rodrigues; Conde, J.his article addresses the theoretical effect of using geothermal boreholes enhanced with macro-encapsulated phase change materials (PCM) employed with a ground sourced heat pump (GSHP). The aim being the improvement of the heat pump performance through soil temperature stabilisation, taking advantage from the PCM inherent property of changing phase at a constant temperature, that can be matched with the tempera...
Applying computational fluid dynamics in the development of smart ripening room...
Pássaro, João; Lampreia, Célia; Martins, António; Dias, João; Alvarenga, Nuno; Martins, João; Garcia, João; Santos, Maria Teresa; Coelho, LuísTraditional ewe's cheese producers face certain challenges caused by fluctuating environmental parameters inside the ripening room, which lead to lack of homogeneity in the final product. The present research discusses the application of computer fluid dynamics for simulating the distribution of environmental parameters, predicting the airflow pattern, and identifying critical areas where such parameters could ...
Impact of environmental conditions on the ripening of Queijo de Évora PDO cheese
Lage, Patricia; Borrega, Joana; Lampreia, Célia; Pássaro, João; Caeiro, José; Gonçalves, Elsa M.; Martins, António; Dias, João; Alvarenga, Nuno‘‘Queijo de Évora’’ is a traditional Portuguese cheese from raw ewe’s milk and granted with PDO label. It is ripened traditionally in rooms with empirical control of temperature and humidity. Nowadays, almost all cheese factories use rooms with temperature and humidity control, but still a significant heterogeneity among cheeses is acknowledged due to unequal distribution of environmental conditions.
