In this article, the implications of viscous dissipation on buoyancy-induced heat and mass transfer of a nanofluid flow along a semi-infinite flat plate in an oscillating system is performed, taking into account the impacts of magnetohydrodynamics (MHD), chemical reaction, porous medium and heat sink. The consequences of various flow parameters on the velocity, temperature, and concentration distribution of the nanofluid, as well as the skin friction coefficient, Nusselt number, and Sherwood number has been solved semi-analytically. The basic governing equations have been determined by employing appropriate transformations techniques which result in high nonlinear coupled differential equations with physical conditions. Different types of nanoparticles are considered, and the salient features of all the embedded parameters on velocities, temperature and concentration fields have been displayed graphically and illustrated. It is concluded from the computational analysis that application of viscous dissipative parameter improves the temperature distributions, which consequently speed up the fluid velocity. This model has practical applications in the fields of biomedicine and resonance imaging. In addition, graphical comparison between Narayana and Venkateswarlu (2016) with the present work demonstrate an excellent relationship, thereby authenticating the precision and accuracy of this present work.
