Summary

Usual heat transfer fluids have low thermal conductivity and this disadvantage provides low performance of such fluids. A new method to enhance thermal conductivity is dispersing solid particles into the base fluids. The nanoparticles used in nanofluids are typically made of metals, oxides, carbides, or carbon nanotubes. Common base fluids include water, ethylene glycol and oil. Amongst the various types of nanoparticles, clay nanoparticles are comparatively less investigated, although in chemical processing, such types of nanoparticles play a pivotal role. Clay nanoparticles, for example, were successfully utilized for the conservation of artwork materials such as marble and porous stones, bronze surfaces, bread-made artifacts, and archeological woods and paper. Nanoparticles are also used in various shapes and sizes. However, researchers are continuously working on nanofluids with new developments. A counterexample is Hybrid nanofluids. This is a new group/type of enhanced working fluids, engineered with enhanced thermo-physical properties. The hybrid nanofluids profit from the thermo-physical properties of more than one type of nanoparticles. Nanoparticles and nanofluids, are equally important in all sciences such as chemistry, physics, thermal engineering, and applied mathematics, indeed. Therefore, researchers from various fields are involved in conducting interesting researches on this topic from the theoretical side as well as from experimental aspects. These researchers are interested to develop the concept of nanofluids due to their enhanced thermal properties and energy saving effect. However, there is deficiency/gap in the literature, and we are in need of more theoretical and experimental multidisciplinary research on this topic to achieve industrial success. This special issue includes a variety of scientific topics related to the developments in the field of nanotechnology, heat transfer and chemical processes and encourage the researchers to present their latest original studies on nanofluids.

    Abstract In this paper, we discussed the effect of nanoparticles shape on bioconvection nanofluid flow over the vertical cone in a permeable medium. The nanofluid contains water, Al2O3 nanoparticles with sphere (spherical) and lamina (non-spherical) shapes and motile microorganisms. The phenomena of heat absorption/generation, Joule heating and thermal radiation with chemical reactions have been incorporated. The similarity transformations technique is used to transform a governing system of partial differential equations into ordinary differential equations. The numerical bvp4c MATLAB program is used to find the solution of ordinary differential equations. The interesting aspects of pertinent parameters on mass More >

    Abstract The science of strategy (game theory) is known as the optimal decision-making of autonomous and challenging players in a strategic background. There are different strategies to complete the optimal decision. One of these strategies is the similarity technique. Similarity technique is a generalization of the symmetric strategy, which depends only on the other approaches employed, which can be formulated by altering diversities. One of these methods is the fractal theory. In this investigation, we present a new method studying the similarity analytic solution (SAS) of a 3D-fractal nanofluid system (FNFS). The dynamic evolution is completely… More >
