Abstract

Correction for ‘The effect of wall depletion and hydrodynamic interactions on stress-gradient-induced polymer migration’ by Hossein Rezvantalab et al., Soft Matter, 2016, 12, 5883–5897.

We noticed, after publication of the paper, that the product of the first-order concentration and first-order migration flux was inadvertently left out of the second-order convection–diffusion equation used in calculating the second-order contribution to the concentration field, c⁽²⁾; the correct expression is


−Dc⁽²⁾_,i,i + v_ic⁽¹⁾_,i + (c⁽⁰⁾^m(2)_i)_,i + (c⁽²⁾^m(0)_i)_,i + (c⁽¹⁾^m(1)_i)_,i = 0	(3.14)

with the last term on the left-hand side giving the additional second order contribution. Note that this is simply a typo in writing the expression in the main text, while all the analysis and the results reported for second-order expansion are based on the correct perturbation including the c⁽¹⁾ [J with combining tilde]

^m(1)_i term.
