| Abstract: | The reason of condenser component drag is analyzed when air flows through tilted A-shaped direct air-cooled condenser.Based on numerical and experimental studies,drag coefficients of condenser components are determined when air flows through tilted condenser pipe bank.It is very important to condenser system optimization and economical operation. |
| |
| Keywords: | direct air-cooled condenser drag coefficient tube bundle numerical simulation |
