Special Issue Information

Recent applications in nanotechnology have allowed the development of a new category of fluids termed nanofluids. A nanofluid refers to the suspension of nano-size particles, which are suspended in the base fluid with low thermal conductivity. The base fluid, or dispersing medium, can be aqueous or non-aqueous in nature. Due to the suspension of nanoparticles, one can increase the heat transfer coefficient and consequently enhance the heat transfer value and performance of base fluids. Nanofluids also strengthen solar energy applications, such as heat exchanger design, and some medical applications, including cancer therapy and safer surgery, by heat treatment. Investigations on entropy in nanofluid could be based on numerical/analytical simulations or experimental data that extend the bounds of existing methodologies to new contributions addressing current challenges and engineering problems. The submitted manuscripts must be related with entropy generation in complex and simple fluid models. Furthermore, exergy analysis and entropy generation in different systems, i.e., heat exchangers with distinct sizes from micro- to conventional and renewable energy devices are welcome.

Potential topics dealing with (but not limited to) the following subheadings are deemed suitable for publication:

  • Theoretical advancement and measurements of entropy in nanofluid flows;
  • Theoretical advancement and measurements of entropy in nanofluid flow-enhanced phase change materials;
  • Numerical simulation related to potential applications;
  • New innovative areas of entropy in nanofluid flows in engineering;
  • Critical assessments and future directions of entropy;
  • Entropy generation through porous media;
  • Nanomaterial and nanofluid preparation and characterization (nanoparticles, nanofluids, nanoPCM, nanosalts, ionanofluids, etc.) with entropy generation;
  • Entropy generation and MHD flows.

Our aim is for this Special Issue to provide an overall picture and up-to-date findings to readers of the scientific community that ultimately benefit the industrial sector regarding its specific market niches and end users.

Magnetohydrodynamic nanofluid technologies are emerging in several areas including pharmacology, medicine and lubrication (smart tribology). The present study discusses the heat transfer and entropy generation of magnetohydrodynamic (MHD) Ag-water nanofluid flow over a stretching sheet with the effect of nanoparticles shape. Three different geometries of nanoparticles—sphere, blade and lamina—are considered. The problem is modeled in the form of momentum, energy and entropy equations. The homotopy analysis method (HAM) is used to find the analytical solution of momentum, energy and entropy equations. The variations of velocity profile, temperature profile, Nusselt number and entropy generation with the influences of physical parameters are discussed in graphical form. The results show that the performance of lamina-shaped nanoparticles is better in temperature distribution, heat transfer and enhancement of the entropy generation. Full article

The present analysis deals with the entropy analysis of the blood flow through an anisotropically tapered arteries under the suspension of magnetic Zinc-oxide (ZnO) nanoparticles (NPs). The Jeffrey fluid model is contemplated as blood that is electrically conducting and incompressible. The lubrication approach is used for the mathematical modeling. The second law of thermodynamics is used to examine the entropy generation. The exact solutions are obtained against velocity and temperature profile with the use of computational software. The results for Entropy, Velocity, Bejan number, temperature profile, and impedance profile are discussed by plotting the graphs. ZnO-NPs have promising applications in biomedical engineering due to its low toxicity, economically reliable, and excellent biocompatibility. ZnO-NPs also emerged in medicine i.e., antibacterial and anticancer activity, and also beneficial in antidiabetic treatment. The monitoring of the blood temperature in the case of the tapered artery has supreme importance in controlling the temperature of blood in the living environment. The presence of a magnetic field is advantageous to manage and control the blood motion at different temperatures. The present outcomes are enriched to give valuable information for the research scientists in the field biomedical science, who are looking to examine the blood flow with stenosis conditions and also beneficial in treating multiple diseases.
