摘要:
堵塞已成为滴灌技术的行业难题,是影响滴灌技术发展的关键问题之一。针对这一问题,构建了一种三角环流滴灌灌水器,并开展了基于CFD的水力及抗堵塞特性模拟分析。CFD分析表明,灌溉水中的颗粒粒径与浓度对灌水器流量影响不明显,对灌水器流道内的颗粒浓度分布影响显著,灌溉水中的颗粒粒径越大、浓度越高,灌水器流道内累积的颗粒浓度越大。当灌溉水中颗粒粒径为0.05 mm时,灌水器流道内的最大浓度只有1.582%,而且流道内泥沙颗粒的累积效应不显著,说明三角环流滴灌灌水器具有较好的抗堵塞能力。
Abstract:
Blocking has become an industry problem of drip irrigation technology, which is one of the key problems affecting the development of drip irrigation technology.Aiming at this problem, a triangle circulation drip irrigation emitter was constructed, and the simulation analysis of hydraulic and anti-blocking characteristics based on CFD was carried out.The CFD analysis showed that the particle size and concentration of the irrigation water have no obvious influence on the flow rate, and the particle concentration distribution in the irrigation channel was significant.The larger the particle size and the higher the concentration of the irrigation water were, the larger the accumulated particle concentrations in the irrigation channel.When the particle size of the irrigation water was 0.05mm, the maximum concentration in the irrigation channel was only 1.582%, and the cumulative effect of the sediment particles in the flow channel was not significant, which indicated that the triangle circulation drip irrigation emitters had a better anti-blocking ability.
