Numerical Investigation on the Flow in Tip Clearance of the Last Three Stages of Industrial Steam Turbine

Abstract:

Numerical investigation was conducted on the full-three-dimensional flow in the last three stages of steam turbine using by the commercial computational flow dynamics software CFX. And the equilibrium condensation model was adopted to describe the wet steam two phase flows. This article analyzes the internal flow of the turbine with tip clearance and the structure of the leakage flow.
