利用Fluent仿真模拟技术及同位素示踪方法,对农田水的流动和分布进行了仿真模拟。设置了Fluent同位素标记组分输运模型,并在边界条件中输入了农田水流动参数,包括水的黏度、渗透压力以及水流平均速度等。利用同位素~(18)O示踪法模拟了水流的流动状态,利用反向水文地球化学模拟技术预测了农田水的化学演化规律,为农田水污染治理提供了理论依据。
Using Fluent simulation technology and isotope tracing method, the flow and distribution of farmland water are simulated. The Fluent isotope labeled transport model was set up, and farmland water flow parameters were input into the boundary conditions, including water viscosity, osmotic pressure and average velocity of water flow. Isotope-18 tracer method was used to simulate the flow state of water flow, and the chemical evolution law of farmland water was predicted by reverse hydrogeochemistry simulation technology, which provided a theoretical basis for farmland water pollution control.
