Abstract

The present study scrutinizes slip effects and stagnation point flows of upperconvected Maxwell fluid past a stretching sheet. The non-linear ordinary differential
equations are obtained from the governing partial differential equations and solved
using implicit finite difference method. The impacts of non-dimensional governing
parameters such as Brownian motion parameter, velocity ratio, velocity slip parameter,
suction/injection parameter, Lewis numbers, upper-convected Maxwell parameter,
magnetic field, thermophoresis parameter, chemical reactions parameter, thermal slip
parameter, solutal slip parameter, and heat source parameter on the velocity field, heat
and mass transfer characteristics are discussed and presented through graphs. The
values of local Sherwood number, local Nusselt number, and skin friction coefficient are
discussed and presented through tables. The results indicate that when the magnetic
field is intensified, it reduces velocity profiles and raises temperature and concentration
profiles. Moreover, with an upsurge in velocity slip parameter, the local Nusselt number
and local Sherwood number diminish.
