Abstract
In this paper the energy loss in a circular conduit bend with supercritical flow is analyzed. Based on the test results obtained by a scale model, the energy-loss coefficient has been determined. Simple empirical relationships were developed, describing the effects of the bend curvature and bend deflection angle on the energy losses. Since no expressions for supercritical flow bend energy-loss coefficient exist, proposed empirical relationships have been compared with expressions relating to pressurized flow.
U radu su analizirani gubici energije u krivini koji nastaju pri burnom tečenju u provodniku kružnog poprečnog preseka. Urađena su hidraulička modelska ispitivanja, na osnovu kojih su određeni koeficijenti gubitka energije. Predloženi su izrazi za koeficijent gubitka u zavisnosti od karakteristika krivine (skretnog ugla i zakrivljenosti). S obzirom da u literaturi ne postoje izrazi kojima se opisuje ovakav gubitak energije u krivini, predložene zavisnosti su upoređene sa izrazi a ko i se odnose na tečenje pod pritiskom. Na kraju rada su date preporuke i zaključci.
