Viscoelastic thermal nanofluid flow and heat mass transfer due to a stretching sheet with slip velocity phenomenon and convective heating

Abstract

This work takes into account the heat and mass transfer flow of a viscoelastic thermal over a stretching sheet under the conditions of slip velocity and convective heating. The governing equations of the model, which are nonlinear partial differential equations, are first modified via dimensionless transformation. Here, we suggest that a very hot another fluid may be present beneath the bottom surface of the stretching sheet, which may help to warm the surface by convection phenomenon. The viscoelastic non-Newtonian nanofluid that complies with Walter’s liquid B’ fluid model controls the proposed model. The consequences of thermophoresis and Brownian motion are considered. A numerical methodology based on the shooting method is employed. The results are represented by graphs showing a number of recently significant measures against velocity, temperature, and concentration distributions. In light of the findings, It has been noted that as the effects of Brownian motion and thermophoresis intensify, the thickness of the thermal boundary layer grows clearly. However, the viscoelasticity thins the thermal boundary layer. Finally, comparisons with earlier published data in the literature are done in order to validate the numerical results. There is a fantastic concord.
