TLDR
In this article, the authors presented an analytical study which describes the laminar accelerating flow of a thin film along an inclined wall and found that the non-dimensional film thickness depends on two parameters (Fr/Re and ρu-ratio), the effect of the latter being more pronounced for larger values of the former.About:

Gravity-driven laminar film flow of power-law fluids along vertical walls
TL;DR: In this paper, a theoretical analysis is presented which brings steady laminar film flow of power-law fluids within the framework of classical boundary layer theory, and an exact similarity solution for the velocity field in the film boundary layer is thus made available.

Hydrodynamic entrance lengths of laminar falling films
A. Stücheli,M.N. Özişik +1 more
TL;DR: An integral method was used to obtain a closed form expression for the determination of hydrodynamic entrance length for falling liquid films emerging from a flat slit and flowing in laminar flow along an inclined flat plate as mentioned in this paper.

Developing flow on a vertical wall
K. J. Ruschak,L. E. Scriven +1 more
TL;DR: In this paper, the authors analyzed the laminar flow in a liquid film issuing from a full slot and descending along a vertical wall for the limiting cases of low flow rate and high surface tension.

TL;DR: In this article, an improved integral analysis for the flow in the entrance region of a falling film is presented, in which the effect of the streamwise pressure gradient is taken into consideration.

The measurement of velocities in thin films of liquid
J.O. Wilkes,R.M. Nedderman +1 more
TL;DR: In this article, it was shown that surface active agents at Reynolds numbers corresponding to wavy flow suppressed both the waves and the velocity fluctuations, and that the rate of acceleration of the liquid film to the steady state conditions was determined mainly by surface tension.

Entrance region flows with a free surface: the falling liquid film
Ramon L. Cerro,Stephen Whitaker +1 more
TL;DR: In this article, the von Mises transformation was applied to the Prandtl boudary layer equations to obtain a solution for the free surface velocity profile which was in excellent agreement with experimental data for Reynolds numbers in the range of 145-304.
