Drop-in analysis of an internal heat exchanger in a vapour compression system using R1234ze(E) and R450A as alternatives for R134a
(Elsevier, 2015-10)
The IHX (internal heat exchanger) is introduced in some refrigeration systems in order to achieve higher energy performances. Results obtained vary greatly depending on the refrigerant used and working conditions. This ...

(Springer Verlag, 2016-01)
This paper presents a tool designed to facilitate the communication of environmental information in the ceramic sector, both for companies and products. Specifically, the communication tool allows the environmental product ...
Combining biocatalysts to achieve new phase change materials. Application to non-edible animal fat
(Elsevier, 2018)
The thermal properties of various alkylthreo-9, 10-dihydroxystearates (DHSEs) prepared from non-edible
fat were studied. Non-edible animal fat was hydrolyzed in a 93% yield with R. oryzae resting cells. Crude
unsaturated ...
Polymeric interlayer materials for laminated glass: A review
(Elsevier, 2020-01-10)
Laminated glass is obtained by bonding two or more glass layers using a polymeric interlayer. Compared to monolithic glass, laminated glass is beneficial in terms of post-breakage safety, security against break-ins, and ...
Influence of implementing selective collection on municipal waste management systems in developing countries: A Brazilian case study
(Elsevier, 2018)
The aim of this study is to analyse the evolution of the municipal solid waste management (MSWM) system of João Pessoa (Brazil), which is one of the pioneering Brazilian cities to implement door-to-door selective collection ...
A CFD-DEM solver to model bubbly flow. Part I: Model development and assessment in upward vertical pipes
(Elsevier, 2018-02-02)
In the computational modeling of two-phase flow, many uncertainties are usually faced in simulations and validations with experiments. This has traditionally made it difficult to provide a general method to predict the ...
Ionic compounds derived from crude glycerol: Thermal energy storage capability evaluation
(Elsevier, 2017)
Ionic liquids (diimidazol-1-ium esters) prepared from wastes, crude glycerol and carboxylic acids are investigated as potential phase change materials (PCM). The ionic liquids (IL) with best thermophysical properties were ...
New formulation and characterization of enhanced bulk-organic phase change materials
(2018-02-14)
The main drawbacks faced by researchers to successfully implement organic-PCM as materials to improve the thermal performance of building systems are their low thermal conductivity, their high flammability, and their low ...
Empirical equations for viscosity and specific heat capacity determination of fatty acids
(Elsevier, 2017-04)
Phase change materials (PCM) used in thermal energy storage (TES) systems have been presented, over recent years, as one of the most effective options in energy storage. Saturated fatty acids are one of the most used PCM ...
Geometry optimization of a heat storage system for concentrated solar power plants (CSP)
(Elsevier, 2018)
In the present study, geometry optimization of a phase change material (PCM) heat storage system is presented. The existing PCM-fins heat exchanger system works at the back side of a solar receiver in order to minimize the ...
