CFD modeling of a fixed-bed biofilm reactor coupling hydrodynamics and biokinetics
(Elsevier, 2017-04-01)
Rigorous modeling of transport phenomena is essential to reproduce accurately biofiltration systems performance. In this sense, the aim of this study was to investigate the effect of integrating fluid flow dynamics in the ...
A CFD-DEM solver to model bubbly flow. Part II: Critical validation in upward vertical pipes including axial evolution
(Elsevier, 2018-02-23)
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 ...
Experimental validation of the exact analytical solution to the steady periodic heat transfer problem in a PCM layer
(Elsevier, 2017-12-01)
Phase change materials (PCM) are used in many industrial and residential applications for their advantageous characteristic of high capacity of latent thermal storage by means of an isothermal process. In this context, it ...

(Elsevier, 2018)
The aim of this study is to analyse the evolution of the municipal solid waste management system of João Pessoa (Brazil), which was one of the Brazilian pioneers cities in implementing door-to-door selective collection ...
Rheology of Solar-Salt based nanofluids for concentrated solar power. Influence of the salt purity, nanoparticle concentration, temperature and rheometer geometry
(Elsevier, 2018)
Solar Salt-based nanofluids have attracted significant scientific interest in recent years due to their improved thermal properties, making them strong candidates as thermal energy storage materials and/or heat transfer ...
Non-constant biaxial bending capacity assessment of CFST columns through interaction diagrams
(Korea Institute of Science and Technology Information, 2019)
The mechanical response of concrete-filled steel tubular (CFST) columns subjected to pure compression or uniaxial bending was studied in depth over the last decades. However, the available research results on CFST columns ...
Improvements in the cooling capacity and the COP of a transcritical CO2 refrigeration plant operating with a thermoelectric subcooling system
(Elsevier, 2019-06-05)
Restrictive environmental regulations are driving the use of CO2 as working fluid in commercial vapour compression plants due to its ultra-low global warming potential (GWP100 = 1) and its natural condition. However, at ...
