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 ...
Experimental Investigation of the Efficiency of Heat Pump Drying System with Full Air Recirculation
(Wiley, Hoboken, 2017)
The paper presents results of an experimental investigation of convective drying of apples var. Idared, potatoes var. Desiree and bananas var. Grand Nein, in full recirculation laboratory-scale dryer. The experiments were ...
Numerical simulation of fatigue crack propagation in friction stir welded joint made of Al 2024-T351 alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded T joints has been simulated numerically. Crack propagation in stiffened part of the structure between two ...
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 ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Faculty of Metallurgy, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
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 ...
Water deoxygenation using hollow fiber membrane module with nitrogen as inert gas
(Taylor & Francis Inc, Philadelphia, 2015)
A pilot plant scale fiber membrane system was developed for the removal of dissolved oxygen from water via nitrogen vacuum. Feed water was introduced to the shell side; a nitrogen gas was applied to the lumen side, as an ...
