Analysis of entropy generation minimization in flow of Ree-Eyring nanofluid between two coaxially rotating disks

Present communication addresses MHD radiative nanomaterial flow of Ree-Eying fluid between two coaxially rotating disks. Both disks are stretchable. Buongiorno model is used for nanofluids. Nanofluid aspects comprise random motion particles (Brownian diffusion) and thermophoresis. The considered. Furthermore, dissipation, heat flux Ohmic heating effects considered to the energy equation. Total entropy rate calculated through implementation Second thermodynamics law. Series solutions developed homotopy analysis method. Impacts physical parameters on velocity, temperature, entropy, concentration fields discussed graphically. Skin friction coefficient mass transfer rates numerically calculated. It noticed that velocity liquid decreases vs. higher estimations magnetic parameter while it enhances via larger rotational parameter. Temperature field significantly increases in presence both Brownian diffusion thermophoresis parameters.
