“…Ebaid et al, [32] found that the temperature of Cu/H2O and TiO2/H2O nanofluids has increased along with the enhancement of the slip parameter. Stagnation point flow of Williamson nanofluid towards a permeable stretching/shrinking sheet with partial slip effect has been examined by Khan et al, [31]. The velocity profile has also improved by raising the velocity slip parameter as discussed by Bhattacharya et al, [33] and Aziz et al, [34].…”

The numerical investigation of unsteady magnetohydrodynamic (MHD) stagnation point flow of Al2O3-Cu/H2O hybrid nanofluid past a convectively heated permeable stretching/shrinking sheet with suction/injection effect is underlined. The characteristic of MHD and boundary condition with suction/injection has received a lot of consideration due to its across-the-board application in mechanical and chemical engineering. The governing continuity, momentum and energy equations are transformed into a system of nonlinear ordinary differential equations using similarity transformation, which is then solved using the bvp4c routine. Numerical results are obtained for the skin friction coefficient, local Nusselt number as well as the velocity and temperature profiles for certain values of the governing parameters, namely suction/injection parameter, copper nanoparticle volume fraction parameter and MHD parameter. Results showed that both velocity profile and temperature increase as the suction/injection parameter increases for the first solution and decreases for the second solution. Similarly, when increase the value of MHD parameter M, the velocity and temperature profiles are decreases for both solutions. The magnitude of the reduced skin friction coefficient and the local Nusselt number are notably increased for the first solution with increasing values of the suction/injection and MHD parameters. Finding also revealed that the skin friction coefficient is intensified in conjunction with the local Nussel number by adding up the copper nanoparticle volume fraction. In general, dual solutions are found to exist to a particular extent of the stretching/shrinking sheet.

“…Ajayi et al, [28] discussed viscous dissipation implications in a non-Newtonian Casson fluid flow across a paraboloid of revolution's upper horizontal thermally stratified melting surface. Khan et al, [29] looked into how partial slip influenced Williamson stagnation nanofluid flow over a stretching/shrinking surface. In the fluid flow phenomenon, the outcomes of thermal radiation and heat transfer are crucial.…”

This paper explores the role of thermal radiation, viscous dissipation and chemical reaction on stagnation point flow of Williamson nanofluid over an exponentially stretching sheet. The similarity transformations are performed to extract ordinary differential equations (ODEs) via partial differential equations (PDEs) and the simulation was accomplished by employing homotopy analysis method (HAM). In addition, we evaluated by comparing our findings to those previously described for specific occurrences which are in perfect unison. Skin friction, Nusselt number and Sherwood numbers are captured in the form of graphs and tables for distinct quantities of the flow parameters. The skin friction coefficient improves as the Williamson fluid parameter is elevated.

An unsteady mixed convection flow of Williamson nanofluid over a stretchable surface embedded in a porous medium is scrutinized numerically. Here the porous medium is characterized by Darcy Forchheimer model under the influence of a magnetic field. Heat transfer analysis with two different conditions namely, prescribed surface temperature (PST) and prescribed heat flux (PHF) are taken into account. The evolved mathematical model is numerically solved by utilizing the Keller box method and bvp4c solver in MATLAB. The significance of diverse non-dimensional physical parameters on the considered flow problem is thoroughly demonstrated and discussed for velocity, temperature and concentration profiles through graphs and tables. From the outcomes, it is stipulated that the velocity of fluid enhances with mixed convection and buoyancy ratio parameter whereas switch pattern is spotted for temperature and concentration distributions in both including conditions.
