Special Issue Information

Dear Colleagues,

Nanofluidics is the study and manipulation of fluids confined to nanometer-sized structures. Nanofluids are a class of new engineered fluids that contain nanometer-sized (metallic or non-metallic) particles. Both nanofluids and nanofluidics have been emerging research topics that have attracted plenty of researchers recently. Nanofluidic devices have potential applications in DNA sequencing, epigenetic analysis, gene therapy, drug delivery, and toxicity analysis. Nanofluids have been found to possess enhanced thermo-physical properties, such as thermal diffusivity, thermal conductivity, and viscosity, compared with those of conventional fluids. Thus, nanofluids have been used in industrial cooling applications, nuclear reactors, geothermal power energy sources, automotive fluids and coolants, biomedical applications, and electronic equipment cooling. Because of their miniaturization and high performance, the systems generate very high power (high temperature) densities. As conventional cooling techniques are not providing fast cooling needs for these systems, nanofluids and nanofluidics can play a major role in overcoming such challenges.

As a result of this significance and the potential applications of nanofluidics and nanofluids, this Special Issue is focused on “New Trends of Nanofluidics and Nanofluids” in the Nanomaterials journal to cover recent developments and applications.

Accepted papers are published in the joint Special Issue in Nanomaterials or Nanomanufacturing (https://www.mdpi.com/journal/nanomanufacturing/special_issues/Nanofluidic_Nanofluid).

A numerical treatment for the unsteady viscous-Ohmic dissipative flow of hybrid ferrofluid over a contracting cylinder is provided in this study. The hybrid ferrofluid was prepared by mixing a 50% water (H2O) + 50% ethylene glycol (EG) base fluid with a hybrid combination of magnetite (Fe3O4) and cobalt ferrite (CoFe2O4) ferroparticles. Suitable parameters were considered for the conversion of partial differential equations (PDEs) into ordinary differential equations (ODEs). The numerical solutions were established by expanding the unknowns and employing the truncated series of shifted Legendre polynomials. We begin by collocating the transformed ODEs by setting the collocation points. These collocated equations yield a system of algebraic equations containing shifted Legendre coefficients, which can be obtained by solving this system of equations. The effect of the various influencing parameters on the velocity and temperature flow profiles were plotted graphically and discussed in detail. The effects of the parameters on the skin friction coefficient and heat transfer rates were further presented. From the discussion, we come to the understanding that Eckert number considerably decreases both the skin friction coefficient and the heat transfer rate. Full article
