Abstract
This article presents the investigation relating to the mass and heat transfer characteristics of MHD cop-per-water unsteady incompressible nanofluid flow squeezed within two parallel plates in the presence of applied magnetic field and chemical reaction by employing a systematic method called Differential Transformation Method (DTM) and numerically solved using Runge-Kutta-Fehlberg method. The distinct feature is the inclusion of chemical reaction term of order greater than or equal to one. The governing nonlinear two-dimensional PDEs are altered into ODEs using similarity transformations. The flow, heat and mass transfer results thus found are validated with previous investigations. Effects of squeezing parameter, Eckert and Hartmann numbers on velocity, thermal and mass transfer profiles are analysed and the behaviour of squeeze number on skin friction, Sherwood and Nusselt numbers are dissertated and concluded by means of diagrams. Through this study, it is found that the concentration field reduces for positive values of Cr and rises for negative values of Cr whereas Sherwood number decreases when Cr increases. Increment in order of chemical reaction parameter results in increasing solutal profile.(c) 2022 Elsevier B.V. All rights reserved.
