Abstract
In current attempt, to scrutinize the efficiency of unit, Nusselt numbers as well as skin friction factor were calculated numerically. The unit consists of two plates which rotate and magnetic field was imposed vertically. The carrier fluid is mixture of water and copper and single phase mode was selected due to low concentration. With involve of viscous dissipation impact in energy equation the final equations were obtained. After employ of similarity transformation, ordinary equations were modeled by RK4 and verification test reveals the nice accuracy. Impacts of R and Kr on C-f are in same direction and both have positive effect. The presence of magnetic field reduces the impact of R while it raises the impact of Kr. C-f rises about 1.98% with augment of R when R = 1, M = 0, Kr = 1, and phi = 0.04. Due to greater interaction of nanomaterial in higher volume fraction, the C-f declines with rise of phi and such reduction impact augments if magnetic field imposed. When M = 6, R = 1, and Kr = 1, as phi augments from 0 to 0.04, C-f declines about 6.1%. The growth of Lorentz forces can augment the C-f about 21.70% when R = 0.1, Kr = 1, and phi = 0.04. Nu reduces about 1.16% with rise of M when Kr = 6, R = 1, Ec = 0.04, and phi = 0.04. Nu has reserve relation with Ec and Kr. Both factors make the heat transfer rate to decline. Nu experiences reduction about 4.68% with rise of Ec when Kr = 6, R = 1, M = 9, and phi = 0.04. Positive impact of R on Nu reduces with rise of M.
