Thaum lub plasma yog ib qho tseem ceeb ntawm cov kua Newtonian, cov ntshav tag nrho coj zoo li cov kua dej uas tsis yog-Newtonian uas qhia tag nrho cov cim qhia ntawm non-Newtonian rheology uas suav nrog deformation tus nqi dependency, viscoelasticity, yield stress thiab thixotropy.
Puas yog tib neeg cov ntshav yog cov kua Newtonian?
ntshav ntshav tau raug suav tias yog Newtonian kua rau ntau xyoo lawm. Cov kev sim tsis ntev los no (Brust et al., Phys. Rev. Lett., 2013, 110) tau qhia tias cov ntshav plasma muaj tus cwj pwm viscoelastic hais.
Vim li cas ntshav hu ua non-Newtonian?
Ntshav, ntawm qhov tod tes, nrog rab riam hauv nws, yog cov kua dej uas tsis yog Newtonian. Nws viscosity hloov nyob ntawm seb qhov kev ntxhov siab npaum li cas rau nws. … Nws yog ib qho uas hu ua "shear-thinning" kua--qhov ntau cov ntshav yog agitated qhov tsawg viscos.
Ib co piv txwv ntawm non-Newtonian yog dab tsi?
Ketchup, piv txwv li, dhau los ua khiav thaum shaken thiab yog li cov kua uas tsis yog-Newtonian. Ntau cov ntsev ntsev thiab cov kua roj ntsha uas tsis yog-Newtonian kua, raws li muaj ntau yam khoom siv xws li custard, tshuaj txhuam hniav, hmoov txhuv nplej siab, pob kws hmoov txhuv nplej siab, xim, ntshav, melted butter, thiab tshuaj zawv plaub hau.
Hom dej twg yog ntshav?
Ib qho piv txwv ntawm pseudoplastic kua yog ntshav. Daim ntawv thov no tau txais txiaj ntsig zoo hauv lub cev, raws li nws tso cai rau cov ntshav viscosity kom txo qis nrog nce shear strain tus nqi [20]. Newtonian kua yog ib qho tshwj xeeb ntawm cov uas tsis yog-NewtonianLub sij hawm-ywj siab ntawm cov kua dej uas cov viscosity yog tas mus li.
