Abstract
- Present work addresses the heat/mass transfer mechanism for higher order mixed convective flow of Williamson nanofluid impinging over a nonlinear bidirectional elongating surface with power-law heat/mass fluxes. For scientific relevancy, we also investigated the combined influence of chemical reaction, nonlinear emission of radiation and hydro-magnetic environment on the flow pattern. Novel combination of scaling transformations has been instigated to metamorphose the principal equations into a set of highly nonlinear coupled ordinary-differential equations and then Keller-Box method (KBM) has been utilized to attain the solution of modeled problem. Convergence of the solution has been discussed via grid independence methodology. Controls of sundry dominant parameters on temperature and concentration variations have been discussed via various plots, whereas variations in heat/mass transfer rates are explained through tabular arrangements. Our analysis shows that the Nusslet number and the Sherwood number are developed up-to 38% with the positive estimations of power-law index 0.1≤n≤0.5, whereas thermal gradient θ'(0) is reduced up-to 5% with the appraisal of thermo-migration of nanoparticles 0.4≤Nt≤0.8. Rate of heat transference is improved up-to 24% and the rate of mass transference is improved up-to 5% with the inclusion of nonlinear thermal radiation aspects 1.1≤θw≤1.5. The validation of the solution has been made by comparing the results for restricted cases with the available literature.
