“…Many factors are affecting the oil recovery factor. These are viscosity, density, interfacial tension, and wettability [ 39 ]. However, microscopy allowed us to reveal that the main factor affecting the oil recovery factor is surface wettability.…”

The essential advantages of microfluidic studies are the excellent visualization of the processes of oil displacement from the porous medium model, simple cleaning, and the possibility of the repeated use of the microfluidic chip. The present article deals with the process of oil displacement by suspension flooding using a microfluidic chip, simulating a porous medium, and the suspensions of silicon dioxide nanoparticles (22 nm). The mass concentration of nanoparticles in suspensions ranged from 0.1 to 2 wt%. Five mass concentrations (0.125 wt%, 0.25 wt%, 0.5 wt%, 1 wt% and 2 wt%) were considered. The article presents the experimental photographs of the oil displacement process by water and SiO2 suspension. It is shown that, with the increasing concentration of nanoparticles, the oil recovery factor increases. A significant effect is observed at 0.5 wt% concentration of nanoparticles. It is shown that the increase in oil recovery during flooding by SiO2 suspension with the maximum concentration was 16%.

“…Recently, an approach combining two noted research lines has been actively developing, namely, the geometry of the pore space is restored by core tomography [9], which is subsequently Fluids 2022, 7, 311 2 of 16 used for the application of numerical research methods [10]. In turn, these numerical research methods can be divided into two main approaches: direct 3D simulation (as a rule CFD) [11][12][13] and network (pore-net) simulation [14]. The advantage of the first approach is a detailed understanding of the process, and the disadvantages are the ability to simulate only a very limited core size.…”

“…So recently, one of the methods for increasing the oil return is the use of nano-liquids and this process can be modeled in different ways. For example, by studying the physical properties of a nanofluid experimentally and setting them into a model [12], or trying to construct a simulation of particle motion by an explicitly Langrage method [13]. The second approach allows simulating a core consisting of several million pores [15]; however, it requires a complex procedure for converting the results of core tomography into a network model (based, for example, on the concept of maximal balls [16], or more complex hierarchical approaches [17]).…”

Multiphase flows in porous media are widespread in nature and various technologies. One of the most common examples of this kind of task is the task of recovering oil from the rock. This article describes a mathematical model of the flow of a two-phase (immiscible) liquid based on a new approach of network hydrodynamics for a highly branched microchannel medium (simulating a porous space in the rock). The coupling of the flow and pressure fields in the network is performed using a well-proven SIMPLE algorithm in CFD problems; this approach allows us to use effective approaches to modeling 3D tasks. Phase transfer over the network is carried out by an explicit method with an adaptive time step. The article presents the results of verification of the model, with analytical calculations and in comparison with the results of experimental studies. As an experiment, the displacement of oil from a microchip (Dolomite: 3200284) simulating a porous medium was simulated. The good qualitative and quantitative compliance with the results calculated and the results of the experiment show the correct functioning of the model.

“…The primary physical barrier is situated in the SC, composed of protein-rich dead cells (corneocytes with cornified cytoskeletal components and corneodesmosomes) and lipid-rich structures (lamellar sheets comprising roughly equimolar amounts of free fatty acids, cholesterol, and long-chain ceramides). 5 , 26 The nucleated epidermis also contributes to the barrier through desmosomes, cytoskeletal components, tight junctions, and adherens junctions. Hence, the overall design of the skin, rather than a specific element, determines its efficacy as a protective barrier.…”

Nanosuspensions have garnered recent attention as a promising strategy for mitigating the bioavailability challenges of hydrophobic drugs, particularly those characterized by poor solubility in both aqueous and organic environments. Addressing solubility issues associated with poorly water-soluble drugs has largely resolved the need to enhance drug absorption and bioavailability. As mucosal formulations and topical administration progress in the future, nanosuspension drug delivery, straightforward formulation techniques, and versatile applications will continue to be subjects of interest. Nanosuspensions have undergone extensive scrutiny in preparation for topical applications, encompassing ocular, pulmonary, and dermal usage. Among the numerous methods aimed at improving cutaneous application, nanocrystals represent a relatively recent yet profoundly intriguing approach. Despite the increasing availability of various nanosuspension products, primarily designed for oral administration, only a limited number of studies have explored skin permeability and drug accumulation in the context of nanosuspensions. Nevertheless, the scant published research unequivocally underscores the potential of this approach for enhancing cutaneous bioavailability, particularly for active ingredients with low to medium solubility. Nanocrystals exhibit increased skin adhesiveness in addition to heightened saturation solubility and dissolution rate, thereby augmenting cutaneous distribution. The article provides a comprehensive overview of nanosuspensions for topical application. The methodology employed is robust, with a well-defined experimental design; however, the limited sample size raises concerns about the generalizability of the findings. While the results demonstrate promising outcomes in terms of enhanced drug delivery, the discussion falls short of addressing certain limitations. Additionally, the references largely focus on recent studies, but a more diverse inclusion of historical perspectives could offer a more holistic view of the subject.
