Abstract

Based on previous studies, prediction of flow in the DRAFT TUBE, as a sample of COMPLEX FLOW PHENOMENA, has been shown to be of vital importance in modeling hydroturbine flows.In this research, numerical solutions are presented for the TURBULENT FLOW through the DRAFT TUBE of Masjed-e- Soliman HEPP., a new project constructed during recent years in the south of Iran [5]. The special features of the subject flow, such as rapid curvature, separation, swirl, and vortices require exact physical model investigation and also great challenges in numeric and turbulence modeling aspects.Unfortunately, as the physical measurements provided by the supplier are incomplete, no physical data are available. Thus, using known software (with light background) and grid independence study are two other ways for verification of results. However, this paper demonstrates the capability of CFX-tascflow, a commercial CFD software Widely used for complex flow prediction, and NS3D, a new CFD code developed by LHM. Reynolds-Averaged Navier-Stockes (RANS) equations are solved in both of them and standard k-ε and standard k- w turbulence models are examined In the end, the flow structures are discussed using various graphical post processing results.
