Abstract

A quasi-three dimensional algorithm is developed to simulate two-phase fluid flow and heat transfer in the shell-side of power plant condensers. The simulation method developed is based on the fundamental governing conservation equations of mass and momentum for both vapor-phase and liquid-phase, and air mass fraction conservation equation. In the proposed numerical method, the condenser shell-side is subdivided into number of sectors normal to the cooling water flow direction. The three-dimensional effects due to the cooling water temperature difference are taken into account by a series of two dimensional calculations, each being for one sector. Porous media concept is employed to model the tube bundle. The pressure drop balance concept is used to dete
