MAGNETOHYDRODYNAMIC GO-WATER NANOFLUID FLOW AND HEAT TRANSFER BETWEEN TWO PARALLEL MOVING DISKS

ABSTRACT
The unsteady MHD squeezing flow of nanofluid with different type of nanoparticles between two parallel disks is discussed. The governing equations, continuity, momentum, energy, and concentration for this problem are reduced to coupled non-linear equations by using a similarity transformation. It has been found that for contracting motion of upper disk combined with suction at lower disk, effects of increasing absolute values of squeeze parameter are quite opposite to the case of expanding motion. In this case, radial velocity near upper disk decreases while near the lower disk an accelerated radial flow is observed. The comparison between analytical results and numerical ones achieved by forth order Runge-Kutta method, assures us about the validity and accuracy of problem.
