“…Xu 17 compared the thermophysical properties in Devi and Devi 13 and Takabi and Salehi 15 to examine the three‐dimensional boundary layer flow problem. Also, Khashi'ie et al 18 showed that the numerical values using both types of correlations were in accordance with percent relative error less than 1%. The flow analysis in the laminar boundary layer of hybrid nanofluids is not limited to the deformable flat plate but also to other surfaces as summarized in Table 1 17‐36 …”

“…The thermophysical properties for the water at 25°C and the nanoparticles are presented in Table 3. As discussed earlier in the Section 1, there are also other correlations of hybrid nanofluids (correlations type II) by Takabi and Salehi 15 and used by many researchers 17,18,21,22,33 . The volumetric concentration of hybrid nanoparticles in type II is described as

ϕ_{normalh normaln normalf} = ϕ_{1} + ϕ_{2}

while the dynamic viscosity can be calculated using this correlation

\frac{μ_{normalh normaln normalf}}{μ_{f}} = \frac{1}{{false(1 - ϕ_{h n f} false)}^{2.5}} = \frac{1}{{false(1 - ϕ_{1} - ϕ_{2} false)}^{2.5}} .

“…This study intends to analyze the stagnation point flow with mixed convection toward a permeable vertical Riga plate, which is not considered by Khashi'ie et al 32 Suction through a permeable surface is important in aiding the laminar boundary layer flow from separating to turbulent flow while at the same time, increasing the heat transfer performance of the working fluid. But there are a few studies that reported the inefficiency of hybrid nanofluids in augmenting the heat transfer when dealing with suction in the opposing (shrinking/opposing buoyancy) flows, 18,19,28‐31 including the existence of two solutions 50 . Hence, in this study, the dual similarity solutions are examined in all convective (assisting/opposing/forced) regions in the presence of suction and EMHD parameters.…”

The application of appropriate wall mass suction (transpiration) has been reported as the key factor to generate steady solutions in the opposing flow (shrinking or opposing buoyancy). This study features the impact of the suction and mixed convection parameters in the stagnation point flow toward a permeable Riga plate. Due to the capability of hybrid nanofluids in enhancing the heat transfer performance, the combination of copper (Cu) and alumina (Al2O3) nanoparticles are used, including water as the base fluid. It appears that the dual solutions are potential in this problem with the negligence of the suction parameter. However, this transpiration effect is efficient in delaying the separation process of the hybrid nanofluid flow and enhancing the heat transfer rate. The heat transfer rate augments with the addition of ϕ 2 and S. The increment of heat transfer rate is reported between 34% and 39% when 30% of the suction parameter ( S = 0.3 ) is applied. Besides, the addition of the mixed convection parameter from the opposing to assisting flow enlarges the velocity profile while reduces the temperature profile. The reduction of temperature distribution with an upsurge of suction, mixed convection, and EMHD parameters implies the operating heat transfer process.

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.

The article explores the upshot of Hall current, thermal radiation and magnetic field on hybrid nanoliquid flow over the surface of a spinning disk. The motive of the present effort to upgrade the heat transmission rate for engineering and industrial purposes. The hybrid nanoliquids as comparative to the conventional fluids have higher thermal properties. A special class of nanoparticles known as carbon nanotubes (CNTs) and iron ferrite Fe3O4 are added to the base fluid. The system of modeled equations is depleted into dimensionless differential equations through similarity transformation. The transform equations are further solved through Parametric Continuation method (PCM). For parametric study the embedding flow factors on velocity, energy, mass transmission and motile microorganism’s concentration profiles have been sketched. The obtained results are compared with the existing literature, which shows best settlement. It concluded that the heat transmission rate reduces for Hall current and rises with radiative factor. The results perceived that the addition on CNTs in carrier fluid is more efficacious than any other types of nanoparticles, due to its C-C bond. CNTs nanoliquid can be more functionalized for the desired achievement, which can be utilize for a variety of applications by functionalization of non-covalent and covalent modification.
