Dinamika chastits v vyazkoy zhidkosti: Vliyanie vzaimodeystviya chastits na ikh dvizhenie v vyazkoy zhidkosti vo vneshnikh polyakh (Russian Edition)

Nalichie neskol"kikh faz i ikh vzaimodeystvie mezhdu soboy i vneshnimi polyami yavlyaetsya kharakternoy osobennost"yu lyuboy dispersnoy sistemy. Prichem eto vzaimodeystvie imeet slozhnyy kharakter i poroy privodit k paradoksal"nym rezul"tatam. Dobavka v nesushchuyu fazu chastits s luchshimi fizicheskimi kharakteristikami poroy privodit k ukhudsheniyu svoystv vsey sredy v tselom. Eto rezul"tat nalichiya poverkhnosti razdela mezhdu fazami cherez kotoruyu proiskhodit ikh vzaimodeystvie. Suspenzii (emul"sii) obladayut tem svoystvom, chto dispersnye chastitsy mogut peremeshchat"sya v nesushchey zhidkosti v rezul"tate deystviya kak vneshnikh, tak i vnutrennikh sil (sil vzaimodeystviya). V sisteme zhidkost"-chastitsy sushchestvuyut dva printsipial"no raznykh mekhanizma vzaimodeystviya chastits. Pervyy mekhanizm svyazan s silami, neposredstvenno deystvuyushchimi mezhdu chastitsy. Vtoroy mekhanizm svyazan s gidrodinamicheskim vzaimodeystviem chastits v zhidkosti. Vzaimodeystviem chastits vliyaet na techenie sredy v tselom i, sootvetstvenno, na vse protsessy, proiskhodyashchie v takoy sisteme. V poslednie gody vse bol"shiy interes predstavlyaet modelirovanie dinamiki sistemy zhidkost"-chastitsy. V rabote predstavleny rezul"taty po dinamike chastits v zhidkosti s uchetom ikh vzaimodeystviya.
