Efficient helium cooling methods for nuclear fusion devices: Status and prospects
(Elsevier Science Sa, Lausanne, 2009)
Helium-cooled reactors offer several important advantages as the helium is an inert and neutron transparent gas. compatible with high outlet temperatures and all structural and functional materials considered for plasma ...
Ocena integriteta cevnog sistema vrelovodnog kotla izloženog koroziji / Integrity assessment of hot-water boiler tubing system exposed to corrosion
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2009)
U cilju izvođenja validne procene integriteta komponenti ugrađenih u industrijska energetska postrojenja neophodno je primeniti metodološki pristup koji obuhvata prikupljanje, sistematizaciju i analizu podataka iz ...
Design update, thermal and fluid dynamic analyses of the EU-HCPB TBM in vertical arrangement
(Elsevier Science Sa, Lausanne, 2009)
In the frame of the activities of the EU Breeder Blanket Programme and of the Test Blanket Working Group of ITER, the Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM) is developed in Forschungszentrum Karlsruhe (FZK) ...
Garancijska ispitivanja toplotnih performansi i pada pritiska razmejivača toplote / Acceptance test of thermal performances and pressure drop of heat exchangers
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2009)
U okviru rada prikazana je metodologija ispitivanja razmenjivača toplote u zavisnosti od cilja ispitivanja. Cilj ispitivanja prikazanog razmenjivača toplote je određivanje toplotnih performansi i pada pritiska razmenjivača ...
Unapređenje održavanja dijagnostikovanjem stanja i ponašanja rotornih bagera on-line i off-line metodom / Improvement of bucket wheel excavator maintenance by on-line and off-line method of condition and behavior diagnostics
(Savez inženjera i tehničara Srbije, Beograd, 2009)
Dijagnostika stanja i ponašanja je od presudnog značaja za donošenje pravilnog stava o radu i održavanju rotornog bagera, odnosno svih komponenti bagera, od čelične konstrukcije pa do pogonskih grupa. Da bi jedan rotorni ...
Uporedna analiza inženjerskih metoda u mehanici loma / A comparative analysis of engineering methods in fracture mechanics
(Institut za ispitivanje materijala, Beograd, 2009)
U ovom radu je analiziran Kingov model opruga u nizu za površinske prsline i pokazano je da se, polazeći od analitičkih izraza datih u modelu, mogu izvesti interesantne zavisnosti. Kingov model je upoređen sa modelom opruga ...
Variable Coefficients Model for Drying Processes with Conductive Heat Supply
(Taylor & Francis Inc, Philadelphia, 2009)
The proposed model is for heat and mass transfer inside a layer of moist material placed on hot isothermal surface. The relevant thermophysical properties of the material are considered as fully dependent on local temperature ...
Analiza prigušenja konstrukcije tipa ljuske od legure titana u poređenju sa konstrukcijom od legure aluminijuma / Analysis of structural damping of titanium alloy shell structures as compared with that of aluminium alloy structures
(Institut za ispitivanje materijala, Beograd, 2009)
U ovom radu se razmatra mehaničko ponašanje konstrukcije od legure titana sa aspekta određivanja osnovnih dinamičkih karakteristika. Analiziran je numerički model za konstrukcije legure titana tipa ljuske (osnovni konačni ...
Microstructure Changes of Nickel-Base Superalloys Induced by Interaction with Femtosecond Laser Beam
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
The investigation was performed on nickel-base superalloys, with nickel being the most influential alloying ingredient. After thermo-mechanical preparation and corresponding processing, femtosecond laser beam machining has ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
