摘要

Low Reynolds number fully developed swirl flows through rectangular ducts that are helically twisted along their axis are computationally modeled. The twist ratio ξ (= 180° twist pitch/hydraulic diameter) and rectangular flow cross-section aspect ratio α (= height/width) characterize the duct's geometrical attributes. A parametric numerical study delineates the influence of flow rate (10
