The three-dimensional problem of steady fluid deposition on an inclined rotating disk is illustrated in this study. The governing non-linear partial differential equations are reduced to the nonlinear ordinary differential equations system by similarity transform. The analytical solution applied to solve this system is the Homotopy Perturbation Method (HPM). The velocity and temperature profiles are shown and the influence of Prandtl number and rotation ratio on the flow field and the Nusselt number are discussed in detail. The validity of our solutions is verified by the numerical results.
