Abstract
Lattice Boltzmann Method (LBM) is reported for free surface flow in rough-wall plane duct flow. For this purpose, the partial-slip boundary condition is considered to account for the wall roughness. The pressure pipe flow is selected as a benchmark to validate the method. The effect of partial-slip coefficient on the hydraulic loss and pressure drop at different Reynolds numbers is investigated and discussedFile in questo prodotto:
