Numerical study of Williamson hybrid nanofluid flow with thermal characteristics past over an extending surface

The energy and mass dissemination rate have been studied through Williamson hybrid nanofluid (NF) flow comprised of silver (Ag) and magnesium oxide (MgO) nanoparticles (NPs) past over an extending porous surface. The hybrid nanofluid has synthesized by dispersion of Ag and MgO nanoparticles in the base fluid (engine oil). The effects of the constant magnetic field, thermal dissipation, and heat source are also studied in the present analysis. The above scenario has been designed in the form of a nonlinear system of partial differential equations, which are processed through a similarity framework to the system of dimensionless ordinary differential equations. The results are obtained by the numerical computational approach parametric continuation method. It has been perceived that the velocity contour decreases with rising upshots of porosity parameter K-p and magnetic force M, while enhances with the variation of volume friction coefficient. The increment of Biot number Bi, heat source Q, and Eckert number Ec enhances the energy profile, respectively. Furthermore, the mass conversion rate decreases with the variation of thermophoretic parameters and Schmidt number.

Automated summary

The energy and mass dissemination rate of a hybrid nanofluid comprised of silver and magnesium oxide nanoparticles flowing over a porous surface have been studied. The effects of a magnetic field, thermal dissipation, and heat source on the system were also analyzed. The results showed that the velocity contour decreased with increased porosity parameter and magnetic force, while increased with the variation of volume friction coefficient. The energy profile was enhanced by an increase in Biot number, heat source, and Eckert number. The mass conversion rate decreased with changes in thermophoretic parameters and Schmidt number.
