A new correlation for predicting the thermal conductivity of nanofluids; using dimensional analysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
Thermal conductivity of nanofluids is a key thermophysical property, which depends on concentration and size of nanoparticles, temperature and thermophysical properties of the base fluid. Over last decades, several works ...
Advanced exergy analysis of an aircraft gas turbine engine: Splitting exergy destructions into parts
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
Advanced exergy analysis of an aircraft gas turbine engine is presented in this paper. In this framework, the main exergy parameters of the engine components are introduced while the exergy destruction rates within the ...
Heat exchanger applications in wastewater source heat pumps for buildings: A key review
(ELSEVIER SCIENCE SA, 2015)
Wastewater heat recovery applications are becoming widespread in energy saving applications. A sustainable and low emissions operation in air conditioning and heating processes is achieved by harvesting the otherwise wasted ...
Energy, economic, and environmental analysis of a flat-plate solar collector operated with SiO2 nanofluid
(SPRINGER, 2015)
To overcome the environmental impact and declining source of fossil fuels, renewable energy sources need to meet the increasing demand of energy. Solar thermal energy is clean and infinite, suitable to be a good replacement ...
Techno-economic analysis of a stand-alone hybrid renewable energy system with hydrogen production and storage options
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
In the present study, a hybrid renewable energy system using hydrogen energy as energy storage option is conceptually modeled for the Bozcaada Island in Turkey. The system is investigated from the techno-economic point of ...
Avoidable and unavoidable exergy destructions of a fluidized bed coal combustor and a heat recovery steam generator
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
Advanced exergy analysis was performed using the actual operational data taken from a fluidized bed coal combustor (FBCC) and a heat recovery steam generator (HRSG) in a textile plant located at Torbali, Izmir. First, the ...
Advanced exergoenvironmental assessment of a building from the primary energy transformation to the environment
(ELSEVIER SCIENCE SA, 2015)
Buildings are of great importance in terms of consumption of energy all over the world. Building sector has a significant influence over the total natural resource consumption and is significant contributors of greenhouse ...
Performance enhancement of a Flat Plate Solar collector using Titanium dioxide nanofluid and Polyethylene Glycol dispersant
(ELSEVIER SCI LTD, 2015)
The use of TiO2 water nanofluid as a working fluid for enhancing the performance of a flat plate solar collector has been studied. The volume fraction of the nanoparticles was 0.1% and 0.3% respectively, while the mass ...
Comparison of exergoeconomic analysis of two different perlite expansion furnaces
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
In this study, exergoeconomic analyses of two different perlite expansion furnaces are performed based on the actual operational data. The exergy cost and the cost per unit of exergy of the expanded perlite produced by the ...
Advanced exergoeconomic analysis of a gas engine heat pump (GEHP) for food drying processes
(PERGAMON-ELSEVIER SCIENCE LTD, 2015)
Exergetic and exergoeconomic analyses are often used to evaluate the performance of energy systems from the thermodynamic and economic points of view. While a conventional exergetic analysis can be used to recognize the ...
