Abstract
Flow between two rotating plates with inclusion of nanomaterial was scrutinized in current article. The below plate is not only the melting surface but also it is stretching sheet. Two-phase approach for nanomaterial leads to adding new scalar for concentration and extra terms as source terms in energy equation. Inclusion of magnetic force as well as centrifugal force affects this system. Final equations have one variable (eta) and solved via RK4 to achieve four parameters. Active parameters affect the velocity distributions and velocity boundary layer and these influences were shown in variation of C-f. Lorentz force has direct relation with surface tension and C-f for M = 6 is 1.2 times higher than that of M = 0. Impact of this external force grows with increase of R and delta while it declines with rise of Kr. Growth of Kr from 1 to 3 offers augmentation in C-f about 0.12% and this percentage reaches to 0.07% when M = 6. C-f declines about 1.59% with rise of delta when Lorentz force is zero. All factors reduce the negative impact of M except for R which provides greater negative effect. As M augments from 0 to 6, Nu reduces by 0.67% and 2.08% when R = 0.2 and 0.8, respectively. Nu augments about 16.9% with rise of delta when M = 6. Both Nt and Nb have positive impacts on nanomaterial convective mode and Nu increases with augment of these factors. With growth of Kr, Nu declines about 0.19% and this impact reduces as magnetic force declines.
