The environmental impacts of the use of synthetic surfactants are discussed in this work
such as their high levels of toxicity and low biodegradability. These materials destroy aquatic …

There are two parts to the interaction of foam with porous media. How the foam interacts with
the surface and the flow within the substrate, which is the focus of this review. Flow-through …

The flow of liquid relative to the bubbles is called drainage. This paper presents a study of
the numerical solution of a non-linear foam drainage equation with time-fractional derivative …

In this study, we examine the well-known foam drainage equation in the form of the
nonlinear partial differential equation using a new extended direct algebraic method. This …

We review the most recent studies of drainage/imbibition of foams placed on porous
substrates: the latest theoretical models, simulation studies and experimental observations …

The drainage of foams created using emulsions has been investigated from both
experimental and theoretical point of view. The drainage of emulsion foam is investigated …

Lightweight lignocellulosic fibrous materials (LLFMs) offer a sustainable and biodegradable
alternative in many applications. Enthusiastic interest in these materials has recently grown …

The spreading of small liquid drops over thin and thick porous layers (dry or saturated with
the same liquid) is discussed in the case of both complete wetting (silicone oils of different …

In this paper, a new two-mode version of the foam drainage equation is presented. The new
model describes the motion of instantaneous symmetric double-waves and their interaction …

Multiparticle migration in a wet foam fluid is increasingly found in relevant engineering
applications. The microscopic reciprocal influence between the flowing foam and the settling …
