The quadratic convective flow of Williamson nanofluid with multiple diffusions

Abstract

Abstract The present work will characterize the heat and mass transport phenomena in the nonlinear combined convective Williamson nanoliquid flow along with the moving plate in a continuously moving parallel free stream. The nonlinear thermal radiation and diffusions of chemical species such as liquid Nitrogen and liquid Ammonia are also considered in this analysis. The physical problem is modelled mathematically as a set of nonlinear coupled partial differential equations with suitable boundary conditions. The governing equations are expressed in the dimensionless form by utilizing non-similar transformations. Further, we employ the Quasilinearization technique and implicit finite difference scheme for numerical computation. The results are discussed with the aid of graphs and tables. The drag coefficient, rates of heat and mass transports are pronounced more for higher values of nonlinear convection, while reverse behaviour can be observed for the Williamson parameter. Moreover, the mass transfer rate for liquid Ammonia is approximately 22% more than that of liquid Nitrogen. So obtained numerical results in this analysis are compared with previously published works and achieved an excellent agreement.
