摘要

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 fo rboth vapor-phase and liquid-phase, and air mass fraction conservaton equation. In the proposed numerical method, the condenser shell-sde is subdivided into number of sectors normal to the cooling water flow direction. Teh three-dimensional effects due to the cooling water temperature differnce are taken into account by a series of two dimensional calculations, each being fo rone sector. Porous media concept is employed to mdoel the tube bundle. The pressure drop balance concept is used to determine the inlet mass flow rate for each domain. A finite volume discretization procedure is used to solve the governing equations.
