摘要：
The thermal performance of power plant condenser for 300 MW unit, widely used in China, was numerically analyzed using a porous medium model with distributed flow resistance and mass sink. Four typical tube arrangements, lozenge-shaped, egg-shaped, cap-shaped, double-peak-shaped, were considered. The shell side pressure drops and venting rates of condenser for different tube arrangements were compared, and some roles for tube arrangement were concluded, such as, the bundle profile should be wedge-shaped or double-peak-shaped, auxiliary steam inlet sub-channels and the tapered air cooling region should be designed, etc.
