The characteristic of flow fields in elbow has been numerically studied to develop anti-abrasive elbows, which is typically equipped in coal-burning power plants, for conveying high-velocity particle-laden fluids. Specially, a vortex flow field in the pipe experiencing particle abrasion was formed and particle flow simulation was conducted. The governing equations for three-dimensional, turbulent flow fields were discretized by FVM and solved by the SIMPLE algorithm.
