This article aims to study the magnetohydrodynamics (MHD) viscoelastic second-grade nanoliquid with heat transmission between two parallel plates in a rotating system. The flow of nanoliquid is steady, and the media is supposed porous. The basic governing equations have transformed to a set of nonlinear coupled differential equations using suitable similarity variables. An optimal approach has been used to obtain the solution of the modeled problems. The dissimilarity of the Nusslet number, the Sherwood number, and their effects on the temperature and concentration profiles are analyzed. This work is mainly focused on the influence of rotation, Brownian motion, porosity, and thermophoresis analysis. Moreover, for comprehension, the physical presentation of the embedded parameters, such as the Prandtl number Pr, viscosity parameter R, rotation parameter Kr, Brownian motion parameter Nb, thermophoretic parameter Nt, magnetic parameter M, porosity parameter γ, and Schmidt number Sc, have been discussed graphically. Also, an increase in Brownian motion increases the temperature, whereas an increase in γ, R, and M decrease the velocity field.
