Heat input effect of friction stir welding on aluminum alloy aa 6061-t6 welded joint
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The paper deals with the heat input and maximum temperature developed during friction stir welding with different parameters. Aluminum alloy (AA 6061-T6) has been used for experimental and numerical analysis. Experimental ...
Application and design of an economizer for waste heat recoveryin a co-generation plant
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Energy increase cost has required its more effective use. However, many industrial heating processes generate waste energy. Use of waste-heat recovery systems decreases energy consumption. This paper presents case study ...
Temperature and heat effects on polyethylene behaviour in the presence of imperfections
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
This paper highlights the changes of polyethylene behaviour during various loading rates as well as the influence of test temperature on the material characteristics. Passive infrared thermography method and a high speed ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
Assessment results of fluid-structure interaction numerical simulation using fuzzy logic
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
A fuzzy approximation concept is applied in order to predict results of coupled computational structure mechanics and computational fluid dynamics while solving a problem of steady incompressible gas flow through thermally ...
Heat transfer enhancement through pcm thermal storage by use of copper fins
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Enhancement of heat transfer over a cylinder shaped thermal energy storage filled by paraffin E53 by use of longitudinal rectangular copper fins was analyzed. The thermo-physical features of the storage material are ...
