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 gas and liquid phases, and the air mass fraction conservation equation. In the proposed numerical method, the condenser shell side is subdivided into a number of domains 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 domain. A porous media concept is employed to model the tube bank. The pressure drop balance concept is used to determine the inlet mass flow rate for each domain. A staggered grid is used to perform the discretization. The resulting discretized equations are solved using the SIMPLEC algorithm. The numerical predictions of an experimental steam condenser are compared with the available experimental results. The predicted results are in good agreement with the experimental data. The results also show an improvement over the results obtained using a single-phase model. Sensitivity studies are carried out for four different correlations of condensation heat transfer coefficient.Dept. of Mechanical, Automotive, and Materials Engineering.
