Abstract With the aim to solve the structural problem of complete fluidic sprinkler,a new kind of flui-dic sprinkler—outside signal fluidic sprinkler was proposed,which has outside signal fluidic element and double nozzle. Outside signal fluidic element made it more convenient to adjust. was selected. The high-speed jet were crushed. As a result, its atomization and uniformity coefficient were improved. The structural of double nozzle made the sprinkler more stable.PXH complete fluidic sprinkler for compared experiments. The experimental results demonstrated that,at the same pressure, radius of outside signal fluidic sprinkler is relatively larger than complete fluidic sprinkler,and the average raindrop diameters is about 0.5mm smaller than complete fluidic sprinkler. So the atomization performance of outside signal fluidic sprinkler is more superiority.The shape distribution of outside signal fluidic sprinkler was triangle which is more helpful for combination than complete fluidic sprinkler. The combination uniformity coefficient were simulated using the Matlab program,the best combination distances of outside signal fluidic sprinkler at the pressure of 0.15 MPa,0.2 MPa and 0.25 MPa were R,1.1R and R among the combination distances were chosen,and the combination uniformity coefficient values were 78.3%,83.9% and 87.6% respectively.
