Numerical study of inlet Reynolds number in fine particles deposition processes in a flue gas turbine

In this study, the effect of Reynolds number on deposition in a flue gas turbine is numerically investigated by conducting a study on flow channels between stator blades and rotating blades. The turbulence flow is modeled by the Renormalization-group (RNG) k-ε model, and particle motions are simulat...

Zusammenfassung:	In this study, the effect of Reynolds number on deposition in a flue gas turbine is numerically investigated by conducting a study on flow channels between stator blades and rotating blades. The turbulence flow is modeled by the Renormalization-group (RNG) k-ε model, and particle motions are simulated by the discrete particle model (DPM) with User Defined Function (UDF). Numerical investigation is conducted for particles in the size of dp
