Characterization and modeling of a scroll expander with air and ammonia as working fluid
(Elsevier, 2014-09)
This paper presents the experimental characterization and modeling of a scroll expander. The expander used here is a scroll compressor modified to work as an expander. It is characterized in two experimental setups using ...
H∞ optimization of fluid viscous dampers for reducing vibrations of high-speed railway bridges
(Elsevier, 2014-04)
This work deals with the optimization of fluid viscous damper systems (FVDs) to reduce the resonant dynamic structural response of high-speed railway bridges by algebraic and numerical approaches. The presented method ...
Attitude towards the incorporation of the selective collection of biowaste in a municipal solid waste management system. A case study
(Elsevier, 2014-12)
European waste legislation has been encouraging for years the incorporation of selective collection systems for the biowaste fraction. European countries are therefore incorporating it into their current municipal solid ...
Energetic evaluation of a CO2 refrigeration plant working in supercritical and subcritical conditions
(Elsevier, 2014-05)
Unlike other refrigerants, R744 (or carbon dioxide) has a very low critical temperature (30.98 °C) which hampers working in subcritical conditions especially when the environment is used as a heat rejection sink. Accordingly, ...
SLOD-BI: An Open Data Infrastructure for Enabling Social Business Intelligence
(IGI Global, 2015)
The tremendous popularity of web-based social media is attracting the attention of the industry to take profit from the massive availability of sentiment data, which is considered of a high value for Business Intelligence ...
An experimental study on bubble entrainment and flow characteristics of vertical plunging water jets
(Elsevier, 2014)
When a vertical liquid jet plunges into a liquid surface after passing through a surrounding gas phase it entrains a large amount of gas bubbles into the receiving pool, and forms a large submerged two-phase region with a ...
Retrofit of existing railway bridges of short to medium spans for high-speed traffic using viscoelastic dampers
(Elsevier, 2012)
This paper presents a study on the energy-absorbing capacities of viscoelastic dampers (VEDs) for reducing the resonant vibrations of simply supported high-speed railway bridges of short to medium span. The proposed solution ...
Simulation of bubbly flow in vertical pipes by coupling Lagrangian and Eulerian models with 3D random walks models: Validation with experimental data using multi-sensor conductivity probes and Laser Doppler Anemometry
(Elsevier, 2012)
A set of two phase flow experiments for different conditions ranging from bubbly flow to cap/slug flow have been performed under isothermal concurrent upward air-water flow conditions in a vertical column of 3 m height. ...
Drop-in substitutes for R-600a. Experimental evaluation and optimization of a commercial fridge
(Elsevier, 2022-07-05)
This work aims to validate the hypothesis that refrigerant blends could allow energy savings in real refrigeration systems. For that purpose, five selected blends have been evaluated as drop-in substitutes in a domestic ...
An e-assessment approach for evaluation in engineering overcroweded groups
(Elsevier, 2012-09)
The construction of the European Higher Education Area has been an adaptation challenge for Spanish universities. New methodologies require a more active role on the students' part and come into conflict with the previous ...
