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 ...
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 ...
Stabilization and characterization of a nanofluid based on a eutectic mixture of diphenyl and diphenyl oxide and carbon nanoparticles under high temperature conditions
(Elsevier, 2017-06)
(C12H10O), and it is used as an HTF with a maximum working temperature of 400 °C. However, one of the drawbacks of Therminol VP1 is its low thermal conductivity. In recent years it has been demonstrated that the addition ...
Modelling and experimental investigation of horizontal buoyant gas jets injected into stagnant uniform ambient liquid
(Elsevier, 2017-07)
In this article, an experimental and theoretical study on the buoyant non-condensable gas jet that is injected horizontally into a high-density liquid ambient at different initial conditions is performed. Direct 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 ...
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 ...
Flow structure of gas-liquid two-phase flow in an annulus
(Elsevier, 2008)
The flow structure of gas-liquid two-phase flow in vertical annulus channel has been investigated. The inner and outer diameters of the annular channel were 19.1 and 38.1 mm, respectively. The total height of the test ...
Interfacial area transport of vertical upward air-water two-phase flow in an annulus channel
(Elsevier, 2008)
An experimental study on the interfacial area transport (IAT) of vertical, upward, air-water two-phase flows in an annulus channel has been conducted. The inner and outer diameters of the annular channel were 19.1 mm and ...
A case study on the application of passive control and seismic isolation techniques to cable-stayed bridges: A comparative investigation through non-linear dynamic analyses
(Elsevier, 2015-09-15)
This paper investigates the seismic performance of an existing steel cable-stayed bridge located in a high seismic zone. In 1988 the structure experienced the failure of one of its anchorage plates needing closure and ...
Mainstreaming commercial CSP systems: A technology review
(Elsevier, 2019)
In this review, we summarise the current status and new trends in concentrating solar power (CSP) technology, analysing the technology cost and their evolution during the last years, with special focus on thermal storage. ...
