On the basis of CFD software

the thermodynamic performance of cooling tower in a 600 MW nuclear power unit was compared with that of a thermal power unit with the same scale

under conditions with different wind speeds. Relationship between the unit back pressure and wind speed variation at different environmental temperatures was obtained. The results show that

the larger the air cooling tower's size

the stronger the wind resistance ability. With the same power generation

the size of the air cooling tower in nuclear power unit is far larger than that of the thermal power unit. Therefore

the successful operation experiences of the air cooling towers in thermal power units can be used as the references for that in nuclear power units in future.
