Approximate explicit analytical expressions of friction factor for flow of Bingham fluids in smooth pipes using Adomian decomposition method

This study concerns with the development of explicit expressions of friction factor for the flow of Bingham fluids in smooth pipes in both laminar and turbulent regimes by using a powerful analytical technique, i.e. Adomian decomposition method (ADM) and one of its variant namely restarted ADM (RADM). The results from these expressions match very well with those obtained by well-known correlations and are found to be valid for all practical ranges. It is hoped that the derived expressions will be useful for the researchers working in the area.
