Balancing flow distribution and decreasing the pressure drop in each vapor distributing pipe based on security is the importance of the study of exhaust pipe of direct air cooling power unit. Using computational fluid dynamics software FLUENT

wet steam inside exhaust pipe of high-type and Y-type of a 600 MW direct air cooling power unit are numerical stimulated. Analyses and research the simulated result. Provides assist for exhaust pipe optimal design of direct air cooling power unit.
