Irrigation Uniformity With Complete Fluidic Sprinkler in No-Wind Conditions

Abstract

Abstract:The Complete fluidic sprinkler was originally created by China. Irrigation uniformity in no-wind conditions was studied in this paper. Radial water distribution for complete fluidic sprinkler type 10 was got by experiment. MATLAB was used to establish computation program to change the radial data into net data. Three-dimensional water distribution figures for single sprinkler and combined sprinklers were figured out after the calculation of MATLAB. Combined uniformity coefficient of the complete fluidic sprinkler type 10 was simulated in combined spacing coefficient form 1 to 1.8.The maximal uniformity coefficient was 80.5% or 88.2% for rectangle or triangular combination respectively. Combined uniformity surpasses 75% when combined spacing coefficient was 1 to 1.7 in rectangle combination and 1.4 to 1.7 in triangular combination. A case study shows that the MATLAB is reliable for simulating water distribution in sprinkler irrigation.
