论文摘要
胶体悬浮液的偏离应力通常使用Batchelor引入的表达[J.流体机械。 83，97--117（1977）]。我们以示例表明，其派生中的中心特征，即向下密度梯度驱动颗粒的热力学力与胶体的运动不一致。提出了应力的新表达。
The deviatoric stresses of colloidal suspensions are routinely calculated using the expression introduced by Batchelor [J. Fluid Mech. 83, 97--117 (1977)]. We show by example that the central feature in its derivation, the thermodynamic force driving particles down the density gradient, is inconsistent with the motion of the colloids. A new expression for the stress is proposed.
