Developing efficient water-saving irrigation technologies that utilize high sand-laden water is an important approach to alleviating agricultural scarcity in the Yellow River Basin. This study aims investigate sedimentation patterns and fluid movement characteristics drip emitters under such challenging conditions. The dynamic changes Dra Cu were determined through short-period intermittent clogging tests evaluate anti-clogging performance of four different emitter types. distribution particle size composition deposited sediments inside analyzed using a high-resolution electron microscope laser analyzer. Additionally, RNG k-ε turbulence model was used simulate emitters. results showed B belt had better sediment tolerance operational stability. capacity can be improved by optimizing combination channel structure content. divided into mainstream zone vortex zone. Sediment particles increased backing-water center, where 0.05–0.1 mm more prone settling due reduced transport capacity. Energy dissipation primarily took place at curvature channel, within each unit, gradually decreasing along flow direction, with lowest aligning deposition zones. These findings provide theoretical basis for mitigating systems, offering valuable insights improving effective utilization resources

Applying poor-quality water in drip irrigation has become increasingly common to address agricultural scarcity. However, emitter clogging remains a critical challenge that limits the widespread adoption of this technology. Currently, mechanism under conditions insufficiently explored. This study investigates distribution and accumulation substances within emitters three conditions: saline water, Yellow River 1:1 mixture both, at degrees 5%, 20%, 50% (i.e., flow rate reaches 95%, 80%, rated flow). The results showed when reached led highest volume total substance channel, 1.77 mm3), while 50%, resulted (5.11 use blended improved situation. Under different conditions, mainly formed on upstream downstream faces accounting for 23.9–31.8% 9.3–32.4% volume, respectively. With higher levels, proportion face increased significantly, other areas minimal change. was more pronounced front channel than back across entire length, except 20% degree water. At 5% clogging, largest difference observed with occurred research provides insights into impact suggests blending gradually varying structure, increasing arc can effectively alleviate enhance efficiency.
