带电胶体粒子的热泳

Thermophoresis of charged colloidal particles

S. Fayolle, T. Bickel, A. Würger

摘要:

用流体力学方法研究了带电胶体悬浮液中热致颗粒流动。详细推导了作用在带电边界层上的力密度。从Stokes方程出发,在颗粒表面无滑移边界条件下,得到了颗粒的漂移速度和热泳输运系数。结果进行了讨论,鉴于以前的工作和现有的实验数据。

英文摘要:

Thermally induced particle flow in a charged colloidal suspension is studied in a fluid-mechanical approach. The force density acting on the charged boundary layer is derived in detail. From Stokes' equation with no-slip boundary conditions at the particle surface, we obtain the particle drift velocity and the thermophoretic transport coefficients. The results are discussed in view of previous work and available experimental data.
