Abstract
A new prototype of fluidic sprinkler is proposed in this paper. To determine the discharge coefficient (A), pattern radius (B), sprinkler rotation speed (C), droplet diameter distribution (D), and the radial application pattern (E), several sprinkler heads were specially fabricated to carry out the experiments. After systematic experiments were conducted with the 10PXH fluidic sprinkler, the results showed that the inner contraction angle influenced A, B, C, and E, and the geometrical parameters of offset length and working area length influenced E. The operating pressure influenced B, C, D, and E. The reductions in the radius exactly corresponded to the reduction of the discharge coefficient. As the inner contraction angle increased from 10° to 70°, the pattern radius at 250 kPa decreased from 10.7 to 8.4 m and the discharge coefficient decreased from 0.9 to 0.67. The time per rotation and the droplet diameter distribution were analyzed, respectively. The radial application pattern at 250 kPa for all nozzles was established. For the square configurations, the smaller the lateral spacing, the higher the uniformity.
