In the deﬁnition of the Lewis number on page 4, left column, 5 lines before Eq. (5) in Ref.1, we noticed a mistake that we would like to amend.

The deﬁnition provided in the original paper states that the Lewis number Le is

Le = D/D_T, (1)

where D is the mass diffusion coefﬁcient and DTis the thermodiffusion coefﬁcient.

The correct deﬁnition of the Lewis number is2–4

Le = D/κ, (2)

whereκ is the thermal diffusivity of the ﬂuid mixture.

We would like to thank Oliver Lötgering, presently Ph.D. student at the University of Stuttgart for ﬁrst pointing out the mistake.
