dc.description.abstractU ovom radu analizira se uticaj širine i položaja breše na svojstvo konzervativnosti računske sheme Makormak (MacCormack). Svojstvo konzervativnosti ispituje se praćenjem relativne greške zapremine nastale numeričkom simulacijom isticanja vode iz rezervoara kroz otvor formiran trenutnim delimičnim rušenjem brane. Razmatraju se dva položaja breše - breša koja se formira uz jednu od obala i simetrična breša fomirana na sredini širine kanala. Razmatrane breše zauzimaju 10% i 50% ukupne širine korita. Takođe se analizira i slučaj potpunog trenutnog rušenja brane.sr
dc.description.abstractIn the present paper influence of a width and a position of a breach on the conservative property of the MacCormack scheme is analysed. Investigation into the conservative property of the scheme is conducted through examination of the volume-balance relative error arising from the numerical simulation of the shock-wave propagation induced by instantaneous, partial dam-breach. Two characteristic positions of the breach are analysed. One near the bank, and the other, in the middle of the channel and symmetrical to its axis. Breaches spreading over 10% and 50% of the total channel width are analysed. In addition to instantaneous partial dam-breach, total instantaneous breach is analysed, too.sr
