Abstract: An energy dissipation model is presented for the computation of unsteady friction losses adapted to smooth-to-rough transition and fully rough pipes. The eddy viscosity model used to compute the Reynolds stresses in turbulent ...

Abstract: A new model for the computation of unsteady friction losses in transient flow is developed and verified in this study. The energy dissipation in transient flow is estimated from the instantaneous velocity profiles. The ...

Abstract: This paper presents equations developed by using genetic algorithms (GA) to estimate decay coefficients for instantaneous acceleration–based (IAB) unsteady friction models in order to predict energy dissipation following ...

Abstract: There is a need for regulation and control of irrigation conveyance systems for sustainable agriculture. Design and analysis of hydraulic structures within complex channel systems are essential for conservation and efficient ...
