Numerical study of a power plant condenser tube arrangement

Comparison of power plant steam condenser heat transfer models for on-line condition monitoring

“…Hu and Zhang developed improvements to turbulence [10] and inundation [11] modelling for numerical condenser simulations. Zeng et al [12] developed 3-D models of three power plant condenser configurations, and compared the results to HEI correlations. While the 3-D models are likely the most accurate option in the absence of extensive proprietary data available to condenser manufacturers, the difficulties of modelling two-phase flow, phase change and interaction of the two phases will still produce significant uncertainties in the results.…”

Three-dimensional numerical model for the two-phase flow and heat transfer in condensers

“…Later, Rusowicz [30] performed the simulation using a single-phase two-dimensional steady state model on a 50 MW plant condenser and reported satisfactory results. Zeng et al [4] solved the single-phase mixture equation for the mixture of steam and non-condensable gases in addition to the RNG k-e model to study the effect of different tube arrangements for a 300 MW power plant condenser.…”

“…The design of condensers has traditionally been conducted by experienced designers through trial and error approach based on previous designs, or tests [2][3][4][5]. However, a detailed knowledge of the flow field and heat transfer in condensers is required in order to design a reliable and efficient unit, and the traditional methods do not provide this level of details.…”

Turbulence modeling for the two-phase flow and heat transfer in condensers

“…Sha et al [26] proposed a one-equation turbulence model based on transport equation for turbulent kinetic energy to account for tube-bundle resistance. Later, several researchers [3,[27][28][29] solved the k-e equations to model the turbulent viscosity in the vapor-air mixture, and finally, Zeng et al [30] implemented the RNG k-e turbulence model in their numerical solution without considering the effects of tube bundles and two-phase interactions on the turbulence.…”
