On the stagnation point flow of nanomaterial with base viscoelastic micropolar fluid over a stretching surface
Abstract
Two dimensional Maxwell micropolar fluid flow over a stretching surface is considered in the current analysis. We have highlighted the impacts of viscoelasticity to analyze the flow behavior under the assumptions of nanomaterial over a stretching surface. We also considered the effects of MHD and slip effects for both suction/injection cases. The micropolar non Newtonian nanofluid flow has been presumed in the steady case. Using the boundary layer assumptions and the micro-interia theory for Maxwell nano fluid we have presented the two dimensional momentum equations. This system has become dimensionless when we applied the similarity transformations. The dimensionless system has solved to find the effects of flow behavior through numerical scheme bvp4c method. The physical dimensionless parameters which involved in the flow assumptions are highlighted through graphs and tables. We discussed the skin friction and heat transfer rate as the surface. Some meaningful results are developed which may be helpful in the field of engineering and science. We have been noted that with the increase of δm,σsandρs/ρf, the nondimensional velocity f′(η) increases while temperature θ(η) gives the decline behavior for higher values of δm,σsandρs/ρf. Surprisingly, the skin friction and heat transfer rate at the surface are both increases for enhancing ϕ.
