Study on the Infiltration Reduction Characteristic and the Mathematical Model of the Bilateral Interference Infiltration under Film Hole Irrigation

Based on the indoor experiment of the film hole infiltration,the change rule of the film hole bilateral infiltration and the reduction characteristic of the interference infiltration are found.The three-phase model and the infiltration reduction model of the interference infiltration are set up and the varying regularity of the interference infiltration parameter is probed.According to the data analysis,the concept of the interference infiltration reduction ratio is put forward and the calculating formula for the interference infiltration reduction ratio is established,on the basis of which the power function relation between the infiltration reduction ratio and the time is established.These research results have laid a foundation for further study of the theory and technical parameters of film hole irrigation.
