高压旋转射流喷头参数优化及破土试验研究
Research on parameter optimization and soil-breaking experiments of high-pressure rotating jet nozzles
摘要
Abstract
Aiming at the problem of poor signal performance of the high-pressure water jet target detection due to the interference of media such as soil layers and sand layers covering the surface of deeply buried targets,a method of using high-pressure rotating jet to strip the surface soil layer was proposed to improve the detection efficiency of subsequent high-pressure water jets.The standard k-ε turbulence model and VOF multiphase flow model were applied to study the influence of different nozzle types,rotating elements,and nozzle contraction angles on the pressure loss characteristics of rotating spray head.Numerical simulations and experimental verifications of the soil-breaking efficiency of rotating spray head under different incident angles and spray distances were conducted.The results show that the optimal geometric parameters inside the spray head are as follows:the nozzle type is a conical long straight shape,the rotating element is a single-head with a 12 mm pitch,and the nozzle contraction angle is 30°.On this basis,when the incident angle of the rotating spray head is 60° and the spray distance is 15 cm,the area of stripped soil layer is the largest.The research can provide a reference for the application of high-pressure rotating jets in the detection of large-scale special targets.关键词
