One important indicator of the good performance of rotating sprinklers is the uniformity of *** objective of this experimental study was to investigate the rotation uniformity and water application rate of the newly designed complete fluidic sprinkler in comparison to the widely used impact sprinkler,with the goal to offer recommendations to improve the fluidic sprinkler’s operation ***-sprinkler water application experiments were conducted in accordance with the American Society of Agricultural and Biological Engineers *** completion time through the four quadrants of rotation and water delivery in catch cans were measured at different operating pressures for each sprinkler-nozzle size *** capabilities of Matrix Laboratory were employed to simulate the overlap of adjacent quadrants and to visualize the effect of sprinkler rotation speed variation on water application *** completion time variations were small for both impact and fluidic ***,variations in completion time through the quadrants were higher for the fluidic sprinkler compared to the impact *** higher variations in water application rates were also observed for the fluidic *** optimization of the design features of the fluidic component is necessary to improve rotation stability and to minimize variability in water application rate of the fluidic *** study significantly highlighted some performance qualities of the complete fluidic sprinkler in comparison to that of the impact *** findings of this research will help to improve the efficiency of the new type complete fluidic sprinkler.
