Prediction of the windage heating effect in steam turbine labyrinth seals

Prediction of the windage heating effect in steam turbine labyrinth seals

Today’s steam turbine power plants are designed for highest steam inlet temperatures up to 620°C to maximize thermal efficiency. This leads to elevated thermal stresses in rotors and casings of the turbines. Hence, temperature distributions of the components have to be predicted with highest accurac...
