Theoretical modeling of fluid dynamics and heat transfer in wavy liquid films under complex flow conditions (review)

SP Aktershev, SV Alekseenko… - Thermophysics and …, 2022 - Springer
The review considers problems of fluid dynamics and heat transfer in wavy liquid films under
complex flow conditions. The term “complex conditions” here means the presence of fluxes …

A new family of reduced models for non-isothermal falling films

N Cellier, C Ruyer-Quil - International Journal of Heat and Mass Transfer, 2020 - Elsevier
New asymptotic models are formulated to capture the thermal transfer across falling films.
These models enable us to simulate a wide range of Biot and Peclet number values, without …

Compressibility-induced destabilisation of falling liquid films: an integral approach

P Botticini, G Lavalle, D Picchi, P Poesio - International Journal of …, 2024 - Elsevier
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 …

Active control of liquid film flows: beyond reduced-order models

R Cimpeanu, SN Gomes, DT Papageorgiou - Nonlinear Dynamics, 2021 - Springer
The ability to robustly and efficiently control the dynamics of nonlinear systems lies at the
heart of many current technological challenges, ranging from drug delivery systems to …

Gas-sheared falling liquid films beyond the absolute instability limit

M Ishimura, S Mergui, C Ruyer-Quil… - Journal of Fluid …, 2023 - cambridge.org
We study the effect of a confined turbulent counter-current gas flow on the waviness of a
weakly inclined falling liquid film. Our study is centred on experiments in a channel of 13 mm …

Gravity-driven film flow down a uniformly heated smoothly corrugated rigid substrate

GR Daly, PH Gaskell, S Veremieiev - Journal of Fluid Mechanics, 2022 - cambridge.org
Gravity induced film flow over a rigid smoothly corrugated substrate heated uniformly from
below, is explored. This is achieved by reducing the governing equations of motion and …

Electrostatic control of the Navier-Stokes equations for thin films

AW Wray, R Cimpeanu, SN Gomes - Physical Review Fluids, 2022 - APS
A robust control scheme is derived and tested for the Navier-Stokes equations for two-
dimensional multiphase flow of a thin film underneath an inclined solid surface. Control is …

Thermal insulation performance analysis of high rise building envelope based on finite element analysis

Q Wang - Thermal Science, 2022 - doiserbia.nb.rs
The current analysis method of thermal insulation performance of building envelope
neglects the optimization of temperature control parameters, which leads to poor thermal …
