This paper deals with the resistance of the shed of a steel hall in Drvar according to technical regulations for snow from 1961 and EC1 regulations. The paper aims to check the reliability of the shed with probabilistic approach. That also implies calibration of the steel hall construction analyzed with classic deterministic method. Statical system...

The paper presents the volume-of-fluid (VOF) method for interface capturing in free surface flows in OpenFOAM® software. The VOF-model utilises an algebraic compressive scheme to effectively shrink the transitional region between the liquid and the gaseous phase. The capabilities of the model are demonstrated by simulating two-dimensionalaxisym...

During the second half of the last century in Europe, district heating systems (DHS) have been built intensively to supply cities and settlements with heat energy.Taking into account that energy prices at that time were low, there was an economic justification for the construction of expensive infrastructural distribution systems. After the first o...

The heating of residential and commercial premises in urban areas during winter periods is mostly performed by use of the heat energy which is distributed through central or city heating systems. Water, steam and gas are used as the basic working media in these heating systems. The thermal energy that is used in the city of Kakanj and its surroundi...
