Improvement of cfd models of tunnel fire development based on experimental data
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This paper, dealing with the problems of mathematical description of the tunnel fire development process with the use of experimental data, outlines the procedure of correction of the existing and obtaining of an improved ...
Support vector machine for the prediction of heating energy use
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
Prediction of a building energy use for heating is very important for adequate energy planning. In this paper the daily district heating use of one university campus was predicted using the support vector machine model. ...
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 ...
Health monitoring modular panel interface design and evaluation
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
In this paper we present a conceptual solution of modular panel for measuring health parameters of the elderly. The conceptual solution was followed by a study that analyzed the design and evaluated interface of the system. ...
An experimental investigation and statistical analysis of turbulent swirl flow in a straight pipe
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This paper presents results of our own velocity field measurements in a straight pipe swirl flow. These studies were conducted using an originally designed hot wire probe. Due to the specially tailored shape of the probe, ...
Heat generation during plunge stage in friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
This paper deals with the heat generation in the Al alloy Al2024-T3 plate under different rotating speeds and plunge speeds during the plunge stage of friction stir welding. A 3-D finite element model is developed in the ...
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 ...
Appearance of high submerged cavitating jet: The cavitation phenomenon and sono-luminescence
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
In order to study jet structure and behaviour of cloud cavitation within time and space, visualization of highly submerged cavitating water jet has been done using Stanford Optics 4 Quick 05 equipment, through endoscopes ...
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. ...
