By using the numerical heat transfer(NHT)software Fluent
numerical simulation on flow and heat transfer performance of the novel indirect air cooled radiator of dry cooling tower in a 300MW unit under design condition was conducted.The results show that
with the air fan speed of 100%
the indirect air cooled radicator exhibited the best performance in air direction of 90°
and the poorest in air direction of 45°;the hot air recirculation was the main factor affecting the heat transfer performance.With the air fan speed of 110%
the indirect air cooled radicatior exhibited the best performance in air direction of 90°
and its air resistance capability increased in other air directions;the effect of hot air recirculation significantly reduced;the radiator performance was the worst in air direction of 22.5°.
