Despite its limitations, the Chezy bed shear stress formula is commonly used in depth-averaged flow numerical models as closure for estimating mutual tractive stresses with underneath boundaries. This paper proposes a novel moment-based that could be considered revised version of and can to estimate local variations under more complex varied conditions accelerating–decelerating fields. The depe...

This paper describes a study of spatially accelerating turbulent flow based on the direct numerical simulation with longitudinally moving walls to create relative acceleration between fluid and wall without inducing streamline curvature. The results show broad similarity those previous investigations spatial acceleration, albeit some differences. A new interpretation has been proposed consideri...
