Numerical analysis of a hypersonic turbulent and laminar flow using a commercial cfd solver
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
Computational fluid dynamics computations for two hypersonic flow cases using the commercial ANSYS FLUENT 16.2 CFD software were done. In this paper, an internal and external hypersonic flow cases were considered and ...
Temperature and heat effects on polyethylene behaviour in the presence of imperfections
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
This paper highlights the changes of polyethylene behaviour during various loading rates as well as the influence of test temperature on the material characteristics. Passive infrared thermography method and a high speed ...
The performance of pip-cascade controler in hvac system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Primitive controllers used in the early version for HVAC systems, like the on-off (Bang-Bang) controller, are inefficient, inaccurate, unstable, and suffer from high-level mechanical wear. On the other hand, other controllers ...
Determining the theoretical reliability function of thermal power system using simple and complex weibull distribution
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The main subject of this paper is the representation of the probabilistic technique for thermal power system reliability assessment. Exploitation research of the reliability of the fossil fuel power plant system has defined ...
Thermomechanics of soft inelastics bodies with application to asphalt behavior
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thermomechanical behavior of hot mix asphalt (HMA) is considered. Its highly irregular microstructure is covered by the hierarchical approach. A brief survey of endochronic thermodynamics precedes constitutive consideration. ...
Influence of friction stir welding parameters on properties of 2024 t3 aluminium alloy joints
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced ...
Numerical analysis of temperature field during hardfacing process and comparison with experimental results
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The three-dimensional transient nonlinear thermal analysis of the hard facing process is performed by using the finite element method. The simulations were executed on the open source Salome platform using the open source ...
