Numerical and experimental modelling of turbulent flow in curved channels and diffusers
Original language description
Modelling of turbulent flow in curved channels and diffusers of rectangular cross-section was aimed at the evolution of secondary flow and origin of flow separation and their connection with energy losses and pressure recovery. Numerical results obtainedusing software CFX TASCflow 2.12 were compared with experiments made in a water channel. Flow separation occurs on the inner wall of the channel before the bend exit and its extent is restricted to the central part of the channel due to secondary flow going from the sidewalls to the channel axis. The extent of separation region and consequently the energy losses decrease with the increasing the radius of the inner wall curvature.
