The Effects Of The Cross-Sectional Area And Aspect Ratio Of Beams On A Laminar Channel Flow, Hai-Ping Hu, Rong-Hua Yeh

Journal of Marine Science and Technology

The study analyzed the fully developed laminar flow in a channel with longitudinal rectangular beams arrayed along the channel width. The governing equations describing the fluid which flows along the direction of the beam length are expressed with double Poisson equations and are solved by eigenfunction-expansion and point-match method. The effects of cross-sectional area and aspect ratio of the beams are investigated. Dimensionless velocity profile, mean velocity, and friction factor multiplied by Reynolds number in the channel are presented for analysis. Initially, a comparison of fRe for a special case is made. It is found that the predicted fRe of …
