Mathematical Model of Sprinkler Water Distribution in Micro-Sprinkler Belt Equipment
Today, Shandong Zhongda University is going to introduce the mathematical model of the water distribution of the micro-sprinkler belt equipment to you. I hope it will be helpful to everyone, and let friends who want to know more gain some consensus. Please follow the editor below for a simple understanding.
In order to study the distribution characteristics of the sprinkler irrigation water of the micro-sprinkler belt equipment, according to the data obtained from the single-hole sprinkler irrigation experiment of the micro-sprinkler belt equipment (the water spray angle was designed at 10°～90°), the data fitting method of the DUD nonlinear mathematical model was used. The single-peak and double-peak nonlinear mathematical models of single-hole sprinkler irrigation water distribution in the micro-sprinkler belt equipment are determined. Except for 10° and 90°, the fitting accuracy of the bimodal model is significantly higher than that of the unimodal model for other water spray angles. It can be seen from the regression sum of squares and residual sum of squares of the fitted model that the fitting accuracy of the model is very high, indicating that the nonlinear mathematical model in this paper can better describe the distribution of sprinkler irrigation water in micro-sprinkler belt equipment. This has important guiding significance for further accurately determining the distribution state of soil water movement and for optimizing the design of micro-sprinkler facilities.
