Diffusiophoresis of a soft particle incorporating ion partitioning and hydrophobic core
TL;DR: In this paper , the diffusiophoresis of a soft particle governed by an imposed ionic concentration gradient is studied based on a modified ion transport equation, where the surface of the rigid core of the soft particle is considered to be hydrophobic, which is coated with a charged polyelectrolyte layer (PEL) whose dielectric constant is different from the dispersion medium.

A calculation procedure for heat, mass and momentum transfer in three-dimensional parabolic flows
S.V. Patankar,D. B. Spalding +1 more
TL;DR: In this article, a general, numerical, marching procedure is presented for the calculation of the transport processes in three-dimensional flows characterised by the presence of one coordinate in which physical influences are exerted in only one direction.

Electrophoretic mobility of a spherical colloidal particle
R.W O'Brien,Lee R. White +1 more
TL;DR: In this article, it was shown that for a colloidal particle of any shape the mobility is independent of the dielectric properties of the particle and the electrostatic boundary conditions on the particle surface.

Apparent fluid slip at hydrophobic microchannel walls
TL;DR: In this article, the velocity profiles of water flowing through 30×300 μm channels were measured to within 450 nm of the micro-channel surface and the measured velocity profiles were consistent with solutions of Stokes' equation and the well accepted no-slip boundary condition.
