基于达西定律,分析了饱和区土壤中地下水源热泵抽灌井传热机制,构建了热渗耦合共同作用下的数学模型,研究了有无地下水渗流及渗流速度对抽灌井周围温度场变化的影响,使用COMSOL Multiphysics软件对建立的模型进行了分析模拟。实例结果表明,该模型具有较好的适用性,为系统的优化设计与参数合理匹配提供了理论支持。 Based on Darcy’s law, the heat transfer mechanism of underground water source heat pump pumping well in saturated soil was analyzed, and the mathematical model under the interaction of heat and water coupling was established. The influence of groundwater seepage and seepage velocity on the change of temperature field around pumping well was studied The model was modeled using the COMSOL Multiphysics software. The results of the example show that the model has good applicability and provides theoretical support for the optimal design of the system and the reasonable parameter matching.
