BEM for laminar motion of isochoric viscous fluidŠkerget, Leopold ; Alujevič, AndroV referatu je uporabljen postopek robnih elementov za reševanje problemov gibalne količine in transporta energije v ustaljenem laminarnem nestisljivem židkem fluidu. Prvi pojav opiše Navier-Stokes ... enačba in ohranitev mase, drugega pa difuzivno-konvektivna enačba za temperaturo. Prikazani sta vrtinčno-hitrostna (w-v) in vrtinčno-hitrostno-tlačna (w-v-p) formulaciji za rešitev ravninskih primerov gibanja tekočine. Z vpeljavo vektorja vrtinčnosti je gibalna enačba razpadla na kinetski in kinematski delež. Prvi spet predstavlja difuzivno-konvektivna enačba za vrtinčnost, drugega pa zveza med vrtinčnostjo in hitrostjo.Source: BETECH 86 : proceedings of the 2nd Boundary Element Technology Conference, Massachusetts Institute of Technology, USA., June 1986 (Str. 397-419)Type of material - conference contributionPublish date - 1986Language - englishCOBISS.SI-ID - 117764
