“…Building up of nanoparticles could be through top-down or bottom-up approach routes [2] . Based on physical and chemical properties, nanoparticles are classified into carbon-based [3] ), metallic [4] , ceramic, polymeric [5] , semiconductor [6] and liquid-based [7] . Feasibility of size, facet and shape variation during synthesis gave metallic nanoparticles edge of various applications.…”

“…Polymeric NPs are normally organic-based NPs with a diameter lower than 1 μm. They can be called nanospheres or nanocapsules depending on their composition [68][69][70]. These nanoparticles have the ability to improve both the solubility and the bioavailability of hydrophobic drugs [71] and are intensively used as delivery systems [72,73].…”

Nanoparticles offer a lot of advantageous backgrounds for many applications due to their physical, chemical and biological properties. Their different composition (metals, lipids, polymers, peptides) and shapes (spheres, rods, pyramids, flowers and so on) are influenced by the synthesis methods and functionalization procedures. However, in the medical field, researchers focus on the biocompatibility and biodegradability of the nanoparticles in their attempts for a targeted therapy in which the nanocarriers need to bypass certain biological barriers. Moreover, the increased interest in molecular imaging has brought nanoparticles in the spotlight for their applications in two distinct directions: therapy and diagnosis. Furthermore, recent advances in nanoparticle designs have introduced novel nano-objects suitable as both detection and delivery systems at the same time, thus providing theranostic applications.

“…As mentioned in the previous paragraph, it is noticed that nanoparticles are a wide class of materials depending on the overall shape and size of the materials, peaking the immense interest of researchers in multidisciplinary fields, and can also be utilized in bioimaging applications [22]. Further, they can be employed for drug delivery [23], chemical and biological sensing [24], gas sensing [25], carbon dioxide capturing [26], and other related applications. In the literature [8][9][10][11][12], there is a lack of information regarding the hydrodynamical and thermophysical properties of fluid flow through a permeable channel with reabsorption across the walls in the presence of nanoparticles.…”

Variable Wall Permeability Effects on Flow and Heat Transfer in a Leaky Channel Containing Water-Based Nanoparticles

This work presents the effects of variable wall permeability on two-dimensional flow and heat transfer in a leaky narrow channel containing water-based nanoparticles. The nanofluid is absorbed through the walls with an exponential rate. This situation arises in reverse osmosis, ultrafiltration, and transpiration cooling in industry. The mathematical model is developed by using the continuity, momentum, and energy equations. Using stream function, the transport equations are reduced and solved by using regular perturbation method. The expressions for stream function and temperature distribution are established, which helps in finding the components of velocity, wall shear stress, and heat transfer rate inside the channel. The results show that velocity components, temperature, wall shear stress, and rate of heat transfer are minimum at the entrance region due to the reabsorption of fluid containing nanoparticles. Additionally, with increasing volume fraction of nanoparticles, the rate of heat transfer enhances at all positions inside the channel. Titanium dioxide (TiO 2 ) nanoparticles show higher wall shear stress compared to copper and alumina. The streamlines confirms that all the fluid is reabsorbed before reaching the exit region of the channel for high reabsorption.
