Abstract

The mathematic model for two-phase flow and heat transfer of wet steam in exhausted steam pipeline of the direct air cooling system for a 135 MW power generating unit has been established. Using the computational fluid dynamics(CFD) software

the numerical simulation of exhausted steam state under typical operating condition of the steam turbine has been carried out

the obtained results can provide with help for the optimized design of exhausted steam pipeline for the direct air cooling system.
