“…They showed that the radiation parameter is the main factor of increment of heat capacity of hybrid nanofluid. Ibrahim et al 7 conducted an evaluation to assess the role of a disturber on the enhancement of performance of a solar collector utilizing nanomaterial. They proved that thermal performance enhances about 41.75% with mounting the turbulator and increasing Re leads to augment of exergy performance around 33.09%.…”

Turbulent flow of oil based hybrid nanofluid within an absorber tube of concentrated solar system has been evaluated in this article. To concentrate the solar irradiation, the parabolic plate has been located below the tube and variable heat flux was considered as the boundary condition of the tube. The presence of a turbulator within the circular tube causes secondary flow to increase. Both thermal (Sgen,th) and frictional (Sgen,f) components of irreversibility were reported in outputs. As Re increases, the residence time decreases and lower outlet temperature has been achieved. Sgen,th decreases about 57.36% with growth of Re while Sgen,f increases about 17.44 times. As the number of rows of tapes increases, the value of Sgen,f enhances about 69.23% while the value of Sgen,th decreases around 3.67%. Increase of pitch ratio causes Sgen,th to decrease about 11.25% while frictional component increases around 76.7%.

“…Ullah et al [17] used a CNT-Fe 3 O 4 HNF to simulate the impacts of metallic foam and nanomaterials on the thermal performance of a semisolid heat sink. Using quantitative computations, Ibrahim et al [18] evaluated the influence of distorted circular tubes on improving energy analysis efficacy, as well as the hydrological effectiveness of Cu/water HNF in solar accumulation. Ullah et al [19] studied the effect of concave and convex form on the flow of a radiative hybrid NF (SiO 2 -MoS 2 /water).…”

A three-dimensional Darcy Forchheimer mixed convective flow of a couple stress hybrid nanofluid flow through a vertical plate by means of the double diffusion Cattaneo-Christov model is presented in this study. The influence of high-order velocity slip flow, as well as a passive and active control, are also considered. The motive of the research is to develop a computational model using cobalt ferrite (CoFe2O4) and copper (Cu) nanoparticles (NPs) in the carrier fluid water, to magnify the energy and mass communication rate and boost the efficiency and performance of thermal energy conduction for a variety of commercial and biological purposes. The proposed model becomes more significant, with an additional effect of non-Fick’s mass flux and Fourier’s heat model to report the energy and mass passage rate. The results are obtained through the computational strategy parametric continuation method. The Figures are plotted to reveal the physical sketch of the obtained solution, while the statistical; assessment has been evaluated through Tables. It has been observed that the dispersion of Cu and CoFe2O4 NPs to the base fluid significantly enhances the velocity and thermal conductivity of water, which is the most remarkable property of these NPs from the industrial point of view.
