Increasing knowledge of hybrid nanofluid can be traced to its unique improvement of thermal performance and enhancement of heat transfer rate as applicable in the dynamics of fuel and coolant in automobiles. However, the case of water-based nanofluid conveying three kinds of nanoparticles (i.e., ternary-hybrid nanofluid) with various shapes and densities is far-fetched. The transport phenomena of water conveying smaller densities nanoparticles (i.e., copper nanotubes, graphene, and aluminum oxide) and substantial large densities of nanoparticles (i.e., copper oxide, copper, and silver) of various types through a rectangular closed domain with major emphasis on the significance of suction and dual stretching was investigated. The dimensional equation that model the aforementioned transport phenomenon, for the two cases, were non-dimenzionalized using appropriate similarity variables, parameterized, and solved numerically using shooting techniques together with fourth-order Runge-Kutta integration scheme and in-built bvp4c package of MATLAB. Enhancement in suction and stretching ratio causes the vertical velocity of the motion along x-direction and Nusselt number to be an increasing function. Due to an increase in suction and stretching ratio, fluid flow along (x, y)-directions, temperature distribution, and the local skin friction coefficients are decreasing functions. At all the levels of suction and stretching ratio, higher Nusselt numbers were found in the case of water conveying Copper oxide, Copper, and Silver nanoparticles due to their heavy densities.

The aim of this study is to investigate the influence of carbon nanotubes (CNTs) nanofluid on natural convection with Prabhakar‐like thermal transport, near an infinite vertical heated plate. The generalized memory effect is described by the time‐fractional Prabhakar derivative. Nanofluid flow features such as velocity and temperature are calculated analytically by using Laplace transform. The velocity and heat transfer of Prabhakar‐like fractional natural convection flows of CNTs nanofluids are compared with those corresponding to classical thermal transport, which is described by Fourier's law. The effects of fractional and significant physical parameters are graphically interlined.

In this article, the free convection flow of second‐grade nanofluids based on carbon nanotubes (CNTs) with Prabhakar‐like fractional and Newtonian heating over a vertical plate has been studied. The fractional model of governing equations is defined by the time‐dependent fractional Prabhakar derivative. Using the Laplace transform method, analytical solutions are determined for the dimensionless thermal and velocity profiles. Prabhakar‐like fractional second‐grade fluids with generalized thermal transport velocity and heat transfer are compared with ordinary second‐grade fluids with ordinary thermal transport and ordinary viscous fluids with classical Fourier thermal flux. The effects of fractional and physical parameters are expressed graphically.
