Numerical simulation of non-conventional liquid fuels feeding in a bubbling fluidized bed combustor
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
The paper deals with the development of mathematical models for detailed simulation of lateral jet penetration into the fluidized bed, primarily from the aspect of feeding of gaseous and liquid fuels into fluidized bed ...
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 ...
The effect of welding process and shielding atmosphere on the AlMg4.5Mn weld metal properties
(Carl Hanser Verlag, Munich, 2013)
In this paper, the AlMg4.5Mn alloy has been welded using tungsten inert gas (TIG) and metal inert gas (MIG) processes with different gas shielding atmospheres. Tensile strength, hardness, impact and fracture toughness, ...
Structural life assessment of oil rig pipes made of api j55 steel by high frequency welding
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2013)
Structural life of welded pipes made of API J55 steel by high-frequency (HF) welding has been evaluated. Experimental tests of base metal mechanical properties, including fatigue properties, were conducted on pipes after ...
Longitudinal wheel slip control using dynamic neural networks
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The control of automotive braking systems performance and a wheel slip is a challenging problem due to nonlinear dynamics of a braking process and a tire-road interaction. When the wheel slip is not between the optimal ...
A non-isothermal Couette slip gas flow
(Science Press, Beijing, 2013)
A steady plane subsonic compressible non-isothermal Couette gas flow is analyzed for moderately high and low Reynolds numbers. The flow channel is formed by two plates in relative motion. Two cases are considered: (a) ...
Kinematičko modeliranje hibridne paralelno-serijske petoosne mašine alatke / Kinematic modeling of hybrid parallel serial five-axis machine tool
