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 ...
Quantification of stress raiser influence on decrease of machine parts fatigue life
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
This paper displays the usage of Theory of Critical Distances (TCD) in the prediction of high-cycle fatigue behaviour in machine parts and systems. It is possible to gain real overview of stresses of machine parts by Finite ...
Prediction of crack initiation in spur gear contact zone
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
The objective of this paper is to give a new viewpoint in contact fatigue prediction in the case of high-cycle fatigue. The presented research is based on up-to-date methods and multidisciplinary approach, and enables ...
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 ...
Experimental analysis of artificial hip implant made of titanium alloy
(University of Belgrade, 2012)
Computational and experimental investigation into subsonic flow around a finned ogive cylinder
(Transactions of Famena, 2012)
Experimental and numerical investigation into the flow around an ogive cylinder with fins (missile calibration model) was conducted for Mach 0.6 flow. The computational results were compared to the results of pressure-distribution ...
