Abstract
In the present study, the laminar flow in a rectangular duct with respect to its aspect ratio has been studied using numerical analysis. The aspect ratios investigated ranged from 0.05 to 1, which encompasses values that have been considered in various cases in the past. This study shows that the average friction coefficient varies considerably depending on the aspect ratio. This result can be explained by considering the fact that the laminar flow is determined by the combination of two-dimensional and three-dimensional flows, which are influenced by the wide and narrow sides, respectively. In addition, the influence of the aspect ratio on the entrance length was examined.
