Abstract

Dividing manifold systems have a wide range of applications in the fields of energy transfer and conservation. A uniform flow distribution plays an essential role in industrial processes to improve the efficiency and durability of industrial facilities and equipment. The orthogonal experiment design (OED) was adopted in this study to evaluate the factors that affect flow performance of the dividing manifold systems with parallel pipe arrays (DMS–PPA) under the range of five structural and flow parameters (area ratio (AR), pipe pitch (Δl), height of convex head (hhead), roughness factor (K), and inlet Reynolds number (Rein)). The non-uniformity coefficient (Ф) and total pressure drop (ΔPj) were put forward to evaluate flow distribution. The L25(56) orthogonal array was selected for the experiment, and the analysis of range (ANORA) and the analysis of variance (ANOVA) are performed. The most significant parameter is identified as AR and Rein, respectively, considering the influence degree on the Ф and ΔPj. The effect of AR should be further studied for the structural optimization design of the dividing manifold system.
