Flow networks are abundant in the field of natural science and provides interesting phenomena with potential applications for heat transfer enhancement, flow control and others. An experimental study was performed on cross flow in the bundles of quadrilateral cylinders, including rectangular, diamond-shaped and cross-sectional geometry. Flow visualization by means of the particle tracing method, laser Doppler velocimetry (LDV) and pressure drop measurements using a piezometer were conducted in order to disclose the flow characteristics behind rows of the cylinder inside each bundle. Of most interesting is the finding of periodicity of timewise velocity variation in the vortex region behind each cylinder. The total pressure-loss coefficient is determined as a function of the Reynolds number.
