Numerical study on hygroscopic material drying in packed bed
(Brazilian Soc Chemical Eng, Sao Paulo, 2011)
The paper addresses numerical simulation for the case of convective drying of hygroscopic material in a packed bed, analyzing agreement between the simulated and the corresponding experimental results. In the simulation ...
Instability of equilibrium of nonholonomic systems with dissipation and circulatory forces
(SHANGHAI UNIV, SHANGHAI, 2011)
The paper discusses the equilibrium instability problem of the scleronomic nonholonomic systems acted upon by dissipative, conservative, and circulatory forces. The method is based on the existence of solutions to the ...
Laser Interaction with Material - Theory, Experiments and Discrepancies
(Polish Academy of Sciences, 2009)
The experimental treatment of chosen material with laser beams, starting from continuous wave up to fs pulses, produces the necessity to find the common and sophisticated theoretical approaches to interaction modeling. For ...
Estimation of laser-Doppler anemometry measuring volume displacement in cylindrical pipe flow
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Laser-Doppler anemometry application in measurements of the 3-D swirl turbulent flow velocity in the cylindrical pipe, behind the axial fan, have been analysed. This paper presents a brief overview of uncertainty sources ...
Thermal history and stress state of a fresh steam-pipeline influencing its remaining service life
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
The service life of thick-walled power plant components exposed to creep, as is the case with pipelines of fresh- and reheated steam, depend on the exhaustion rate of the material. Plant operation at elevated temperatures ...
Experimental Investigation of Microcutting Mechanisms in Granite Grinding
(Asme-Amer Soc Mechanical Eng, New York, 2011)
This paper shows the results of investigations performed in the brittle materials microcutting at the Faculty of Mechanical Engineering, Belgrade University. The interactions between a single diamond grain and the machined ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
Reduced Order Numerical Modeling for Calibration of Complex Constitutive Models in Powder Pressing Simulations
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Numerical simulations of different ceramic production phases often involve complex constitutive models, with difficult calibration process, relying on a large number of experiments. Methodological developments, proposed ...
SCANAM method for the assessment of industrial noise
(IOS Press, Amsterdam, 2012)
Work in an industrial environment is often associated with high levels of noise. For measuring and evaluating of noise levels, sometimes it is necessary to use several instruments. These instruments can be very expensive ...
Water Hydrogen Bonds Study by Opto-Magnetic Fingerprint Technique
(Polish Academy of Sciences, 2010)
Hydrogen bond has dual property, classical (electrostatic interaction based on Coulomb's law) and quantum (wave function based on Schrodinger equation). Since Planck's constant is one of the main criteria for decision which ...
