ANALYSIS OF SQUEEZING FLOW OF A VISCOUS FLUID BETWEEN COROTATING DISCS WITH SORET AND DUFOUR EFFECTS

A similarity solution is obtained for the modeled system of differential equations that accounts for the squeezing and rotation effects. The governing equations are coupled with advection diffusion and energy equation which defines heat/mass flux going from the lower to the upper disc. The similarity solution of modeled equations is obtained by the Homotopy Analysis Method (HAM) via mathematica package BVPh 2.0 and is compared with the numerical results obtained by BVP4c to assure the accuracy of HAM. The combined effects of the rotational motion of two discs, upward/downward motion of the upper disc, thermal radiation effect, as well as the Soret and Dufour effects are studied both graphically and numerically.
