A sensitivity analysis is performed to analyze effective parameters on heat transfer and drag coefficient on movable wall. It is found that the mean Nusselt number enhances with Ri number and Ф. It is found that the mean Nusselt number decreases with increasing of Ω and S. To maximize only the mean Nusselt number, the effective parameters are: Ω = 5, Ri = 10, Ф = 0.03 and S = 0.5. To minimize only the drag coefficient the effective parameters are: Ω = 0.9899, Ri = 0.1, Ф = 0.03 and S = 1.
