“…Later, the velocity slip and temperature slip were simultaneously modeled by Alharbi [39] in the study of hybrid nanofluid and the influence of velocity slip is consistent with the result obtained by Hayat et al [35]. Such other studies on slip conditions towards hybrid nanofluid were also reported by Tlili et al [40], Aly and Pop [41] and Eid and Nafe [42]. The reported results in these investigations could provide the initial insight for the engineers and researchers needed to predict and control the slip parameter towards the related applied area.…”

“…With the evolution of nanofluid to hybrid nanofluid, this heat generation/absorption effect has been considered by Hayat and Nadeem [47] with regard to the model of hybrid nanofluid with the three-dimensional flow, which was then continued by Hayat et al [48], who analyzed such effects on the rotating hybrid nanofluid. Eid and Nafe [42] also considered the presence of heat generation together with the slip effect in their research on hybrid nanofluid. Most of them indicated that the amplification of heat generation increases the temperature profile.…”

An investigation has been done on the hybrid nanofluid slip flow in the existence of heat generation over an exponentially stretching/shrinking permeable sheet. Hybridization of alumina and copper with water as the base fluid is considered. The mathematical model is simplified through the similarity transformation. A numerical solver named bvp4c in Matlab software is utilized to facilitate the problem-solving process and dual solutions are attained. The influences of several pertinent parameters on the main physical quantities of interest and the profiles are scrutinized and presented in the form of graphs. Through the stability analysis, only the first solution is considered as the physical solution. As such, the findings conclude that the upsurges of volume fraction on the copper nanoparticle could enhance the skin friction coefficient and the local Nusselt number.

This work addresses the ability to manage the distribution of heat transmission for fluid flow occurs upon a paraboloid thin shaped hot needle by using hybrid nanoparticles containing Copper Oxide (CuO) and Silver (Ag) with water as pure fluid. The needle is placed horizontally in nanofluid with an application of Hall current and viscous dissipation. The popular Buongiorno model has employed in the current investigation in order to explore the impact of Brownian and thermophoretic forces exerted by the fluid. The modeled equations with boundary conditions are transformed to non-dimensional form by incorporating a suitable group of similarity variables. This set of ordinary differential equations is then solved by employing homotopy analysis method (HAM). After detail study of the current work, it has established that the flow of fluid reduces with growth in magnetic effects and volume fractions of nanoparticles. Thermal characteristics increase with augmentation of Eckert number, magnetic field, volume fractions of nanoparticles, Brownian motion parameter and decline with increase in Prandtl number. Moreover, concentration of nanoparticles reduces with corresponding growth in Lewis number and thermophoresis, chemical reaction parameters while increases with growth in Brownian motion parameter.

“…In many of the research studies, the impact of variable thermal conductivity on temperature is not considered. However, from References [35‐37], it can be seen that the effect of variable thermal conductivity is powerfully contingent on temperature, especially if there is a great temperature variance. If relatively a slight temperature variance occurs, it is certainly expected that thermal conductivity will not change, but in the presence of nanoparticles, this supposition can lead to a clear mistake 37 .…”

The effect of viscous dissipation and thermal radiation on mixed convective heat transfer of an MHD Williamson nanofluid past a stretching cylinder in the existence of chemical reaction is analyzed in this study. When energy equation is formulated, the variable thermal conductivity is deliberated. By proposing applicable similarity transformations, nonlinear ordinary differential equations (ODEs) are attained from partial differential equations. These nondimensional ODEs are computed through Runge‐Kutta method integrated with shooting method using MATLAB software. The results found numerically are in agreement with that of the published works of similar nature in a limiting case. The results of the local Nusselt number, skin friction coefficient, and Sherwood numbers are organized in tables. The influence of protuberant parameters on temperature, velocity, and concentration is presented by graphs. From the results, it is seen that for higher values of variable thermal conductivity parameter, the local Sherwood number and skin friction coefficient upsurge, whereas the local Nusselt number diminishes.
