Abstract |
Flow distributions in a rectangular duct with two branch ducts are measured by 5 W laser doppler velocity meter. The fluid flows are also computed by commercial software of STAR-CD for comparison between them. The Reynolds numbers in the main duct are from 4,226 to 17,491. The ratios distributed into two branches from the main duct are invariant to Reynolds numbers according to both of numerical and experimental results. However, computed velocity profiles at exit of each branch are somewhat different from measured profiles at the same location. |
