Numerička optimizacija procesa u ložištu sa aspekata emisije NOx i efikasnosti energetskog kotla / Numerical optimisation of processes in the furnace considering NOx emission and efficiency of utility boiler
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2013)
Razvijen je matematički model, namenjen za predviđanje procesa u energetskim parnim kotlovima TE Kostolac B tangencijalno loženim sprašenim lignitom. Model je primenjen za numeričku analizu rada kotla radi smanjenja emisije ...
Analysis of fouling factor in district heating heat exchangers with parallel helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This paper presents the results of measurements of thermal performance of 8 heat exchangers with parallel helical coils. Measurements were conducted in substations in 2 district heating systems in Serbia: Belgrade and ...
Bucket chain excavator: Failure analysis and redesign of the counterweight boom supporting truss columns
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The supporting truss of the counterweight boom is a vital part of the bucket chain excavator's (BCE) superstructure. The occurrence and propagation of cracks in the supporting truss columns' heads may lead to BCE collapse. ...
Analiza rasta prsline u zonama spoja frikciono zavarenog mešanjem korišćenjem proširene metode konačnih elemenata / Crack growth analysis in friction stir welded joint zones using extended finite element method
(Institut za ispitivanje materijala, Beograd, 2013)
U ovom radu je prikazana analiza rasta prsine u zonama zavarenog spoja izvedenog postupkom frikcionog zavarivanja mešanjem (FSW). Ploče od legure aluminijuma 2024-T351 su sučeono zavarene primenom postupka FSW. Ploče su ...
Advanced seismic slope stability analysis
(Springer Verlag, 2013)
The objective of this study was to present an advanced methodology for assessing seismic slope stability by taking into account the uncertainties related to the main input parameters. The methodology was applied on a real ...
Kinematska analiza uređaja za prostornu dezorijentaciju pilota / A kinematics study for a spatial disorientation trainer for pilot training
(Savez inženjera i tehničara Srbije, Beograd, 2013)
Prostorna dezorijentacija predstavlja jednu od najvećih pretnji za pilote modernih borbenih aviona. Tokom vremena razvijeni su različiti simulatori leta sa ciljem da simuliraju što realnije uslove leta. Uređaj za prostornu ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
