The surfaces are constant and flow regularly in (one dimension, two-dimension .Their system of equations are available for the ( pressure - velocity) analysis ,however, these equations cannot be applied in general problem where surface unsteady and flow in three dimensions. The problems of machines related to low load-carrying capacity. Need to develop the mathematical model by creating a complex system containing many of parameters and depended on perturbation technique to find results so using Ansys analysis of the results, the journal contributes to great knowledge and improved in modern scientific and engineering journal.
