抄録

The X-shaped intersecting flow is shown in staggered bundles of cylinders. The staggered arrangement is more effective from the heat transfer and fluid control standpoint. Experiments using a particle tracing method were performed to visualize the flow in the staggered bundles. In order to determine the flow mechanism, the velocity and pressure variations in the flow field were measured using a two-dimensional laser Doppler velocimetry and a piezometer, respectively. It is disclosed that the flow characteristics depend on the aspect ratio, the diagonal distance and the centrifugal force generated by flowing around each cylinder. The characteristics of hydraulic resistance and dominant frequency for power spectrum in tube banks are also determined.
