Effect of Wind on Recirculation of Direct Air-Cooled Condenser for a Large Power Plant

The paper introduces thermal buoyancy effects to experimental investigation of wind tunnel simulation on direct air-cooled condenser for a large power plant. Recirculation ratio of each measuring point is calculated by measuring temperature at the inlet of fans and outlet of finned tubes under different velocities and wind direction angles. The influence of wind velocity and wind direction on recirculation ratio is investigated. And the relationship between heights of wind wall and recirculation ratio under cooling tower is also discussed.
