Mhd Of Williamson Micropolar - Nanofluid Flow Over A Nonlinear Stretching Sheet: A Numerical Investigation.

This computational study examines a Williamson-micropolar nanofluid flow over a nonlinear stretching sheet subjected to a magnetic field. The Williamson fluid model, known for its ability to describe non-Newtonian shear-thinning behavior, is commonly applied in industrial polymers sheet extrusion. To highlight the influence of the involved parameters on the profiles an adequate mathematical model is formulated. Similarity transformations are used to convert the governing partial differential equations into a system of coupled nonlinear ordinary differential equations. The bvp4c solver of Matlab software is used to solve equations using the Lobatto III finite difference discretisation method with prior verification of the code developed. The impact of various physical parameters are explained and presented through graphs, tables and summarized in conclusion.The main result is that the relevant Williamson micropolar-nanofluid provides substantial improvement in thermal performance and reduced skin-friction can be gained.
