Analiza anizotropnosti turbulentnog vihornog strujanja / Anisotropy analysis of turbulent swirl flow
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
U radu su primenjene dve vrste invarijantnih mapa kako bi se procenio stepen anizotropnosti turbulentnog vihornog strujanja. Korišćene su invarijantna mapa, koju su predložili Lamli i Njuman, kao i baricentrična mapa. ...
Fenomeni nelokalnog turbulentnog prenosa i negradijentne toplotne difuzije u KGH sistemima / On the non-local turbulent transport and non-gradient thermal diffusion phenomena in HVAC systems
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
Istraživanje strukture turbulencije je neophodno za razumevanje fizike strujno-termodinamičkih procesa u KGH sistemima. Analiza i proračun ovih sistema zasnovani su na poznavanju turbulentnog prenosa i njegovom modeliranju. ...
Numeričko istraživanje stišljivog turbulentnog vihornog strujanja sa raslojavanjem polja totalne temperature u cevi / Numerical research of compressible turbulent swirl flow with energy separation in a cylindrical tube
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Cilj ovog rada je numerička analiza fenomena raslojavanja polja totalne temperature u turbulentnom stišljivom vihornom strujanju u cilindričnoj cevi. U tom smislu, raslojavanje polja totalne temperature u vrtložnoj cevi ...
Experimental and numerical analysis of flow field and ventilation performance in a traffic tunnel ventilated by axial fans
(Srpsko društvo za mehaniku, Beograd, 2018)
To investigate air flow in longitudinally ventilated traffic tunnels, a scaled model of a typical road-traffic tunnel with an appropriate ventilation system based on axial ducted fans, is designed and built in the Lab. The ...
Estimation of wind turbine blade aerodynamic performances computed using different numerical approaches
(Beograd : Srpsko društvo za mehaniku, 2018)
Although much employed, wind energy systems still present an open, contemporary topic of many research studies. Special attention is given to precise aerodynamic modeling performed in the beginning since overall wind turbine ...
Towards viable flow simulations of small-scale rotors and blade segments
(Beograd : Srpsko društvo za mehaniku, 2021)
The paper focuses on the possibilities of adequately simulating complex flow fields that appear around small-scale propellers of multicopter aircraft. Such unmanned air vehicles (UAVs) are steadily gaining popularity for ...
INTEGRAL AND STATISTICAL CHARACTERISTICS OF THE TURBULENT SWIRL FLOW IN A STRAIGHT CONICAL DIFFUSER
(Srpsko društvo za mehaniku, Beograd, 2018)
The results of the experimental investigations of the turbulent swirl flow in a straight conical diffuser with inlet diameter 0.4 m and total divergence angle 8.6 degrees are presented in this paper. The incompressible ...
Influence of the Reynolds number on the statistical and correlation-spectral properties of turbulent swirl flow
(Belgrade : Serbian Society of Mechanics ; Mathematical Institute of the Serbian Academy of Sciences and Art, 2014)
Average velocity distributions of the turbulent swirl flow for four Reynolds
numbers, obtained with one-component laser Doppler anemometry (LDA) and stereo
particle image velocimetry (SPIV) behind axial fan in the pipe, ...
Investigation of the turbulent swirl flow in pipe generated by axial fans using PIV and LDA methods
(Serbian Society of Mechanics, Belgrade and Mathematical Institute of the Serbian Academy of Sciences and Arts, Belgrade, 2015)
In this paper is presented experimental investigation of the turbulent swirl ow in pipe generated by axial fans. Two various models of industrial axial fans are used. One of these is axial fan W30, model AP 400, Minel, ...
