Abstract

A quasi-three-dimensional numerical model is proposed to predict the performance of large power plant condensers. The proposed model is applied to a 350 MW power plant condenser under two different loading and operational conditions to demonstrate its predictive capability. The predictions are compared with the experimental data. The comparison is favorable. The equations governing the conservation of mass, momentum, and air mass fraction are solved in primitive variable form using a semi-implicit consistent control-volume formulation in which a segregated pressure correction linked algorithm is employed. The modeling of the condenser geometry, including the tube bundle and baffle plates, is carried out based on a porous media concept using applicable flow, heat, and mass transfer resistances.
