Dvodimenzijski matematični model transporta lebdečih plavin = A two-dimensional mathematical model of suspended sediment transportKrzyk, Mario ; Četina, MatjažǂPo ǂkratki predstavitvi teoretičnih osnov hidrodinamičnih značilnosti tokov, ki jih obravnavamo kot dvorazsežne v vodoravni ravnini, z globinsko povprečnimi hitrostmi, je v prispevku predstavljena ... enačba transporta lebdečih plavin, ki je uporabljena v matematičnem modelu. To je advekcijsko-difuzijska enačba z dodatnim izvornim členom, ki opisuje spremembokoncentracije plavin, povzročeno z usedanjem ali dvigovanjem materiala z dna struge. Globinsko povprečno vrednost koncentracije lebdečih plavin smo dobili na podlagi analize transportne enačbe v navpični ravnini. Izračun izvornega člena sloni na transportni enačbi, definirani v navpični ravnini, ki daje značilen razpored koncentracije lebdečih plavin z najmanjšo koncentracijo na površini in največjo na dnu struge. Rezultati izračuna so odvisni od razlike med vtočno (izračunano) globinsko povprečno koncentracijo plavin in povprečno vrednostjo koncentracije plavin v ravnovesnem stanju, za določene hidrodinamične pogoje znotraj kontrolnega volumna. ...Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Letn. 49, št. 3, 2003, str. 173-184)Type of material - article, component partPublish date - 2003Language - slovenian, englishCOBISS.SI-ID - 6256667
