The nanofluids have acquired substantial attention in the last few decades, due to the improved thermophysical properties such as density, viscosity, thermal conductivity, and specific heat capacity. From the literature, it is noticed that nanofluids find numerous applications in diverse areas including petroleum industry, lubrication, surface coating, biomedical, environmental remediation, and electronics cooling systems. This special issue comprises the theoretical/experimental research

This issue consists of 29 manuscripts which are divided into six sections, namely, heat transfer of nanofluids in cavities and annulus, boundary layer analysis with nanofluids over different geometries, transport properties of non-Newtonian nanofluids over plates, dispersion and stability analysis of nanofluids, heat transfer in channels, and dynamics of nonlinear flows. These sections elucidate the impacts of several effects on transport characteristics of various nanofluids over different geometries. In this issue, the transport properties of various non-Newtonian nanofluids such as the Carreau nanofluid, Casson nanofluid, Jeffrey nanofluid, Maxwell nanofluid, Oldroyd-B nanofluid, power-law nanofluid, third-grade nanofluid, and Williamson nanofluid are presented graphically and the results are discussed with an adequate physical interpretation. Section I of this issue summarises the results on heat transfer of nanofluids in cavities and annular. Aly et al. [1] analysed the natural convection flow resulting from rotating circular cylinders in a horizontal wavy cavity fully filled by a nanofluid. An incompressible smoothed particle hydrodynamics method is used to examine the horizontal wavy cavity which is saturated with three layers of heterogeneous porous media. The results revealed that an increase in the radius of the inner cylinders enhances the temperature distributions and the a
