Abstract

In the previous research, static pressure recovery coefficient (SPRC) and total pressure loss coefficient (TPLC) were used to evaluate the aerodynamic characteristics of exhaust passage of steam turbine. In this paper, the heat transfer performances of condenser are used to evaluate the aerodynamic characteristics of exhaust passage. The aerodynamic characteristics of exhaust passage are optimized through installing guide devices considering the influence of the whole last stage. The computational fluid dynamics software is applied to numerically solve N–S equation and k-ε equation in three dimensions. Then the flow field and the heat transfer performances of condenser were simulated, which using porous medium model and UDF condensation program. The results show that the heat transfer performances of condenser are improved obviously after the flow field of exhaust passage is optimized. The heat transfer coefficient of condenser increases by about 37.5% and the vacuum (VAC) increases by about 0.9 kPa.
