• A new analytical approximate expression for pseudo-plastic annular flow calculations. • Mathematical demonstration of the zero shear rate position's expression. • A good precision for a large range of geometric and rheological parameters. • Simple and explicit expression for further sensitivity or parametric investigations. This work deals with the zero shear rate (maximum velocity) position parameter λ of a steady laminar axial annular flow of power-law fluids especially polymeric ones. λ is involved in the shear rate, velocity profile and the flow rate calculations, which are essential for studies such as viscous dissipation, convective heat transfer and pressure drop prediction in annuli. However, the analytical explicit expression of λ remains unsolved despite some approximate solutions. In this paper, we will provide a simple and analytically demonstrable expression of λ so that it can be used for parametric investigations, identifications, sensitivity analysis etc. in terms of industrial or laboratory applications.
