TLDR
In this paper, the response of turbulent flow to abrupt changes in pipe wall roughness is studied and it is shown that a circumferential flow will not develop near the wall in a pipe with a short patch of circumferentially varying roughness.About:

Effect of secondary flow on droplet distribution and deposition in horizontal annular pipe flow
TL;DR: In this paper, the authors compare the behavior of the droplets (dispersed phase) with and without secondary flow, using large-eddy simulations, and show that the presence of secondary flow increases droplet concentration in the core of the pipe and the droplet deposition-rate at the top of pipe.

Liquid film formation on the inner surface of the horizontal channel
TL;DR: In this paper, the role of large scale waves, or disturbance waves, in the formation of liquid film on the side wall of a horizontal channel is investigated, and the thinning process of liquid thinning as the function of time is also investigated by a simple liquid flow model.
