COMPLEX STAGE – Influence of Seal Leakage Flows Interactions on Steam Turbine Efficiency

Jun 7, 2021

PROJECT TITLE:

Influence of Seal Leakage Flows Interactions on Steam Turbine Efficiency
 

PROJECT DESCRIPTION:

The detailed study of the seal leakage interaction with the main flow, especially in the High- and Intermediate pressure steam turbine stages, is the aim of the project. It is mainly a systematic research of this complex flow by the numerical and experimental approaches. The goal of the research is description of flow structures, formulation of loss model and design of the new turbine stage seals structures. With the new approach the stages efficiency is believed to increase of 0.2 – 0.5% depending on a specific stage conditions.
