Abstract. The present paper considers the suspension as a two-component
mixture, and the following fields have been defined: speed (of the suspension),
microrotation velocity and concentration distribution. The balance equations
are given for the mixture as a whole, whereby the nonlocal effects are
included through the constitutive equations. The expression obtained for
the speed of suspension has been prepared for a graphical presentation,
and subsequently graphically represented and compared with the corresponding
expressions for the case of the classical suspension theory (the local
theory, the symmetric stress tensor), and with the suspension having a
nonsymmetric stress tensor in the local theory.
KRETANJE
SUSPENZIJA SA NESIMETRIČNIM TENZOROM NAPONA U NELOKALNOJ TEORIJI
U ovom radu suspenzije se posmatraju kao dvokomponentne
mešavine a date su sledeće oblasti: brzina (suspenzije), brzina mikrorotacije
i raspodela koncentracije. Ravnotežne jednačine su date za celu mešavinu
dok su nelokalni efekti uključeni u konstitutivnim jednačinama. Izrazi
dobijeni za brzinu suspenzije su pripremljeni za grafičko prikazivanje
i kasnije grafički pokazani i uporedjeni sa odgovarajućim izrazima za slučaj
teorije klasičnih suspenzija (lokalna teorija, simetrični naponski tenzor)
i sa suspenzijama koje imaju nesimetrični naponski tenzor u lokalnoj teoriji..
