Adane, K. K., Auteur ; Ormiston, S. J., Auteur ; M. F. Tachie, Auteur |A numerical investigation of turbulent flow in a draft tube with and without an opening (slot) in the top of each of its three outlet channels is presented. A commercial CFD code, CFX-5, is used to solve the Reynolds-averaged Navier-Stokes equat[...]

G. F. K. Tay, Auteur ; D. C. S. Kuhn, Auteur ; M. F. Tachie, Auteur |This paper reports an experimental investigation of the effects of wall roughness and favorable pressure gradient on low Reynolds number turbulent flow in a two-dimensional asymmetric converging channel. Flow convergence was produced by means of[...]
