“…Amjad et al [ 3 ] studied the MHD Williamson nanofluid with the Cattaneo–Christov (CC) heat flux model across an exponential stretching sheet. As a result of its usefulness, several researchers [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ] have used the Williamson model to show the true behavior of fluids throughout the previous decade.…”

This research work describes and investigates Williamson nanofluid flow over an exponentially stretching permeable vertical plate with temperature-dependent thermal conductivity and viscosity. The governing non-linear partial differential equations (PDEs) are metamorphosed into coupled non-linear ordinary differential equations (ODEs) by using similarity transformation. The succeeding equations were numerically solved using MATLAB function bvp4c for various values of parameters. For velocity, temperature, concentration, the skin friction coefficient, and the local Nusselt number, data are presented in the form of graphs and tables. It is noted that for increasing values of magnetic parameter , Williamson parameter and viscosity parameter , the boundary layer thickness of the velocity profile decreases, while it increases for the temperature profile. The findings of the present work are validated through the published results.

The purpose of the study is to discuss the comparison of the linear and nonlinear stretching sheets on the heat transfer over a curved surface spiraling in a circle with radial distance R. Additionally the consequences of Soret-Dufour in the presence of injection velocity and heat source/sink are investigated in the article.Silver and Copper Oxide are taken as hybrid nanoparticles with water as foundation fluid. Leading equations are converted to nonlinear ordinary differential equations taking some relevant transformations and solved with the combination of the shooting method and RK-4th order method. MAPLE software is used to plot graphs and numerical charts. Flow features are examined for different pertinent parameters. Physical quantities like Sherwood number, Nusselt number, and so forth, are evaluated numerically for different nondimensional numbers. The result substantiates that improving the Dufour number boost the fluid flow and fluid temperature but the opposite behavior is seen in the concentration profile. It is observed that a linearly stretching sheet gives better fluid behaviors compared to nonlinear stretching sheet.

“…Ghasemi and Hatami 23 claimed that growing the Brownian movement factor results in greater outline temperatures and a thicker thermal barrier layer. Ahmed et al 24 reported magneto‐flow of Williamson nanofluid over an exponential permeable stretching curved surface. Different investigations examine the problem of magnetofluids/nanofluids flow and heat transport are reported by many researchers 25–35 …”

The performance of nanofluid in the heat transport phenomena showed satisfactory results, which have been considered by scientists and researchers. The dispersion of two nanoparticles to form a mixture which named as hybrid nanofluid. It has been proved experimentally that hybrid nanofluid has good thermal performance compared to unitary nanofluid. The present study inspected the convective flow of a Williamson hybrid nanofluid through a cone and wedge in a porous medium of different shapes of nanoparticles (cylindrical‐, spherical‐, blades‐, platelets‐, bricks‐) under the influence of a magnetic field. The partial differential equations were converted to an ordinary differential equation and the resulting equations were solved using the bvp4c MATLAB code. The effect of some important physical parameters on both the velocity and temperature profile was graphically plotted and the effect of the shape and size of nanoparticles was discussed, the numerical values of the friction coefficient and Nusselt number were obtained. As observed, the friction factor of Ag–TiO2–H2O hybrid nanofluid was more than that of TiO2–H2O nanofluid. A significant enhancement in bulk temperature is seen for the Ag–TiO2 hybrid and nanofluid formed by blade‐shaped nanoparticles followed by cylindrical, platelet, brick, and spherical nanoparticles. In addition, for a 5% volume fraction of using blade nanoparticles shape givean increase in skin friction factor about 4.8% compared tobrick hybrid nanoparticles. A comparative study of different forms for Ag‐TiO2was presented graphically.
