Passive control by changing the manifold shape is performed for multiple-passage channel flows. As for the manifold shape, the effects of manifold volume and corner curvature are investigated. The multiple-passage is a parallel flow type, and consists of the five branch channels. The channel flows are investigated from the view point of flow uniformity and pressure loss. Experiments are performed for the Reynolds number based on the bulk velocity and hydraulic diameter at the inlet channel from 6.0×102 to 2.0 ×103. The wall static pressure is measured, and the pressure loss and flow rate in the branch channel are evaluated. The uniform flow distribution is realized by increasing the volume of the outlet manifold. The pressure loss is reduced by rounding the corners of the outlet manifold.
