Industrial cooling tower design and operation in the moderate-continental climate conditions
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
A large number of producers offer a wide choice of various types of industrial cooling towers. Usually, a proper choice of pre-fabricated cooling tower satisfies end-user needs. However, if there are specific end-user ...
Energy efficiency improvement by gear shifting optimization
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
Many studies have proved that elements of driver’s behavior related to gear selection have considerable influence on the fuel consumption. Optimal gear shifting is a complex task, especially for inexperienced drivers. This ...
Analytical and experimental determination of the temperature field on the surface of wall heating panels
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
This paper presents experimental verification of the accuracy and acceptability of Faxen-Rydberg-Huber analytical expression for determining thermal characteristics of the heating panels. The verification of accuracy of ...
