Compressibility-induced destabilisation of falling liquid films: an integral approach (P. Botticini)
Title: Compressibility-induced destabilisation of falling liquid films: an integral approach
Speaker: Paolo Botticini
Affiliation: Università degli Studi di Brescia (Italy)
Abstract:We revisit the classical 2D problem of a gravity-driven liquid layer down an inclined plate (Kapitza, 1948), relaxing the usual assumption of homogeneous fluid. We set out to answer three major issues. When the fluid density is allowed to vary, (i) how does this feature structurally affect the formulation of a low-dimensional depth-averaged model? (ii) To what extent and (iii) by virtue of which physical mechanism does compressibility participate in the long-wave interfacial instability? To provide the relevant a...

VERY GOOD EXPLANATION OF LIS
That's very good
very interesting and informative lecture . we very much appreciate the knowledge shared by you.
Fabulous work!
Fabulous work!
Hi
Very interesting talk ! Great work. I would simply note that it is not surprising that stacking different porous media with "discrete gradation" does not extend the operating map in the space (flow rate, equivalence ratio). Upstream conjugate heat transfer is very likely to be very low between two porous plates, whilst necessary to extend the operating limits thanks to the heat recirculation. So obviously, a continuously-printed medium will work better.
very interesting talk!
This video is fantastic. I will send my CV as soon as possible. I hope my background and resume can fulfill your high standards. Keep posting videos like this. These are really motivating. Good luck to all members of PoreLab.
Nice 💯💯
