Numerical Model of L.P.C. Flow Path With Leak System of Powerful Steam Turbine Unit

Numerical Modeling of Wet Steam Flow in Steam Turbine Channel

In power station practice, work is extracted from expanding steam in three stages namely High Pressure(HP), Intermediate Pressure(IP) and Low Pressure(LP) turbines. During the expansion process in the LP turbine, the steam cools down and at some stages, it nucleates to become a two-phase mixture. It is well-acknowledged in the literature that the nucleating and wet stages in steam turbines are ...

Steam turbine model

In order to characterize the transient dynamics of steam turbines subsections, in this paper, nonlinear mathematical models are first developed based on the energy balance, thermodynamic principles and semi-empirical equations. Then, the related parameters of developed models are either determined by empirical relations or they are adjusted by applying genetic algorithms (GA) based on experimen...

Numerical Simulation of Flow Fields in Diaphragm Gland of Steam Turbine

The leakage characteristics of the bending-teeth gland, which may be helpful for the fast start and fast stop of the steam turbine, was discussed in this paper by using ANSYS6.1 software. By compared the flow fields in straight-teeth gland and bending-teeth gland, the methods for the bending-teeth gland to decrease the steam leakage was proposed. The results show that, although the leakage of t...
