Abstract
U radu su analizirane prijelazne pojave koje nastaju prilikom puštanja segmenta vrelovodne mreže u rad. Dan je opis dijelova mreže koji se puštaju u rad zajedno s protokolom puštanja dionice te je izveden matematički model nestacionarnog strujanja kapljevine koji se rješava numeričkom metodom karakteristika. Na kraju su dani rezultati u kojima su uspoređene nestacionarne pojave za više različitih vremena otvaranja kuglastog ventila čija je promjena koeficijenta lokalnog gubitka poznata. Ti rezultati pokazuju da se za različita vremena otvaranja ventila tijekom puštanja vrelovoda u rad ne pojavljuju pulsacije tlaka koje bi mogle biti opasne za rad i funkcionalnost vrelovoda.
Abstract (english)
In the work, transient phenomena occurring during the commissioning of a heating network segment were analyzed. A description of the network components that are put into operation, along with the commissioning protocol of the section, was provided, and a mathematical model of unsteady fluid flow was derived, solved using the method of characteristics. Finally, the results were presented, comparing unsteady phenomena for various times of opening the ball valve, whose change in the coefficient of local mechanical loss is known. These results indicate that for different valve opening times during the commissioning of the heating network, pressure pulsations that could be dangerous for the operation and functionality of the network do not occur.
