analytical solutions and analyses of the displacement separating point in diffusers

The main purpose of this study is to develop an understanding of the turbulent boundary layer calculation to analyze displacement of the separating point in diffusers. an approximate method has been used which is based on an analogy with the rheological power law and is applied in the study of non-linear viscous flows. at first, the method has been validated with the experimental data in the same experimental cases study. an appropriate geometric with and without the nano-fluids in the straight-wall and curved-wall conical diffusers has been investigated. its analyses output was compared with the results obtained by a numerical code. also, the proposed method is more practical and can be used in diffuser design procedures.
