Abstract

The expression for the boundary condition of the solution types (ii) and (iii) at the bottom (z = 0), Eq. (27) in the original paper, is incorrect. The correct version is (1)V0=−duδdx(ζ−ζ2Δ+ζ33Δ2−Δ3)−(U∞−uδ)[(−1+2ζΔ−ζ2Δ2)dζdx+(13−ζ2Δ2+2ζ33Δ3)dΔdx]Accordingly, Eq. (29) in the original paper is changed to (2)(w−η)[14−7w+3w2+(11−w)η−10H(w+η)(1+η)+4(1−w)3R2(w+η)]=ρ[4(1+w+3w2)+2(1+9w)η−152R2(w+η)2{1−w+ηH(1−w)}]where η=h2/2. Actually, there are multiple solution branches of w and η satisfying Eq. (2). Among them, the physically realistic solutions are those with (i) a zero or negative flow rate, and (ii) a positive thickness of the vapor boundary layer, which is represented by (3)−η<w≤η3(see Eqs. (9) and (22) in the original paper).
