In Ref. [1], the Marangoni number M is defined as
$M=γω=μa$
(1)

where $μ$ is the kinematic viscosity with unit $kg m−1 s−1$ (see Nomenclature), and $a$ is the fluid thermal diffusivity (m2 s−1). Therefore, in the original manuscript by Lin et al. [1], the Marangoni number is presented as a number with unit, instead of a dimensionless number. After a communication with the authors, they responded that the correct unit of $μ$ is m2 s−1, and therefore, the Marangoni number is correct.

On p. 3 in the paper by Lin et al. [1], there are two expressions of the shear stress. The first expression is
$τxy=γ|∂U/∂Y|n−1∂U...$
