چکیده
|
The three-dimensional problem of steady fluid deposition on an inclined rotating disk isillustrated in this study. the governing non-linear partial differential equations are reduced to thenonlinear ordinary differential equations system by similarity transform. the analytical solution appliedto solve this system is the homotopy perturbation method (hpm). the velocity and temperature profilesare shown and the influence of prandtl number and rotation ratio on the flow field and the nusselt numberare discussed in detail. the validity of our solutions is verified by the numerical results.
