摘要:Abstract(#br)A theoretical model of effective viscosity of nanofluids considering the effect of inter-particle potentials is developed by mathematical methods. Repulsive DLVO potential of charged particles are selected to express the inter-particle potential and a compact form of...

摘要:Abstract(#br)The non-equilibrium molecular dynamics method is used in the present study to investigate the local effective viscosity in nano-scale shear-driven gas flows. The profiles of gas velocity and shear stress across the channel are sampled and the Newton law of viscosity ...

摘要:Abstract(#br)A theory of the effective viscosity η s of a concentrated suspension of porous spheres (soft particles with no particle core) consisting of uncharged polymers in a liquid of viscosity η is presented. We assume that polymer segments are regarded as resistance cent...

摘要:...(#br)This study investigated the relationship between the tertiary oil recovery by polymer flooding and the effective viscosity of polymer solution. Twenty-eight sandpack flood tests were conducted using oils with viscosities ranging from 430 mPa s to 5500 mPa s. Results showe...

摘要:Abstract(#br)Nanoconfinement of a polymer film affords a reduction of the glass transition temperature ( T g ) and effective viscosity (η eff ). Early on, Prof. Tisato Kajiyama pioneered the idea of enhanced polymer mobility at the free surface. This concept is now well est...

摘要:... An expression for the effective viscosity of the suspension, valid for any solid concentration, is obtained from the homogenization technique. When this special two-dimensional medium is isotropic on the macroscopic scale, upper and lower bounds are derived for its effective viscosity...

摘要:Abstract(#br)An exponential model is proposed for evaluating the effective viscosity of a particle–fluid mixture. First, theoretical consideration is restricted to the dilute condition without effects of dynamic particle interactions and fluid turbulence. This leads to a po...
