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 ...
Characterisation of High-Carbon Steel Surface Welded Layer
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2010)
In this paper microstructural and mechanical properties of high-carbon steel surface welded layer obtained with self-shielded flux cored wire are presented in standard rails and crossings. The testing results of tensile ...
The influence of buffer layer on the properties of surface welded joint of high-carbon steel
(Institute of Metals and Technology, 2011)
Surface welding with buffer layer is often in use because of its well-known properties of plasticity, or ability to slow crack growth initiated. However, in modern surface welding technologies, buffer layer is rarely used. ...
Determination of a Light Helicopter Flight Performance at the Preliminary Design Stage
(Strojniski Vestnik/Journal of Mechanical Engineering, 2010)
Promising solutions for the problem of the extensively time-consuming modern urban transportation has been found in the use of light and very light helicopters. This paper presents a part of the preliminary design methodology, ...
The possibilities for measurement and characterization of diesel engine fine particles: A review
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error ...
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 ...
Thermomechanical modelling the resistance welding of PbSb alloy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
The analytical modelling of the PbSb alloy resistance spot welding process has been developed on the basis of mathematical analysis of thermomechanical conservation laws. The numerical solution of partial differential ...
Prompt system redesign: Shifting to open source technology to satisfy user requirements
(ComSIS Consortium, 2010)
The paper describes a redesign project undertaken in a short period to adapt a software system to user needs. Additional goals of the project included a shift to Open Source software and the selection of technology to ...
Improvement of algorithm for numerical crack modelling
(Springernature, London, 2010)
For numerical simulation of crack modelling in fracture mechanics the eXtended finite element method (Xfem) has been recently accepted as a new powerful and efficiency methodology. In the paper we present the details of ...
Numerical and experimental strength analysis of fire-tube boiler construction
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Norms, such as EN 12952-3 and EN 12953-3 handle the issues concerned with calculation of the pressurized boiler components, not however considering the influences of thermal strains that are often of vital importance for ...
