Groundwater heat pump selection for high temperature heating retrofit
(Elsevier Science Sa, Lausanne, 2012)
Retrofitting of fossil fuel powered hot water radiator heating systems of the existing buildings by groundwater heat pumps can provide significant energy savings followed by economic and environmental benefits. The paper ...
API J55 Steel Casing Pipe with an Initial Surface Crack under Internal Pressure - Determination of Fracture Parameters
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
Seam casing pipe used in an oil drilling rig, manufactured by high frequency (HF) contact welding of API J55 steel, is tested. The influence of an initial defect (machined surface crack) is analysed, by performing pressure ...
Energetic and environmental sustainability of sub-geothermal heat pump heating in Serbia
(Journal of Environmental Protection and Ecology, 2012)
Feasibility of low enthalpy geothermal waters incorporation in Serbian energy source structure has been investigated. Energy potential of ground waters of modest temperature levels is usually neglected since they can not ...

(University of Belgrade, 2012)
Prospects of wind energy sector development in Serbia with relevant regulatory framework overview
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The growth of the renewable energy sector in the world in the first decade of the twenty-first century was rapid. Wind energy sector was one of the fastest growing renewable energy technologies. In this paper, authors have ...
Influence of forward scattering on prediction of temperature and radiation fields inside the pulverized coal furnace
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
A possibility of simplification of the scattering phase function of a pulverized coal flame was analyzed in the paper. It was showed that the type of radiation scattering of a pulverized coal flame is between two limiting ...
Determining the influence of an air wave caused by a passing train on the passengers standing at the platform
(Inderscience Enterprises Ltd, Geneva, 2012)
This paper presents the results of research on the influence of an air wave, caused by a passing train on a person standing on the station platform. The tests were conducted in a real environment, at a railroad, on a doll ...
Micromechanical analysis of mechanical heterogeneity effect on the ductile tearing of weldments
(Elsevier Sci Ltd, Oxford, 2012)
The objective of this study is determination of the effect of mechanical heterogeneity on ductile crack initiation and propagation in weldments using micromechanical approach. Welded single-edge notched bend (SENB) specimens ...
The fundamental role of fluid dynamic analyses in the design of the solid EU Test Blanket Module
(Elsevier Science Sa, Lausanne, 2012)
In the frame of the activities of the European Test Blanket Module Consortium of Associates, the Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM), the so-called solid TBM, is developed in Karlsruhe Institute of ...
