|
摘要
建立单井循环换热地能采集井的Stokes-Darcy流耦合数学模型,利用该数学模型分析实际工程的温度场分布及热物性对换热效果的影响。结果表明:Stokes-Darcy流耦合模型是准确分析单井循环换热地能采集系统的一种有效方法,该方法与传统方法相比具有较高的精度,可为科学利用地热资源提供重要依据。
In this paper,it is established that coupled Stokes-Darcy mathematical model about SWGECCHE,then weuse the mathematical model to analyze the temperature field of the typical project. It is also discussed the heat transfereffect caused by thermal physical parameters. The results of the paper showed that coupled Stokes-Darcy flows model is akind of effective method to research the SWGECCHE and the model has higher accuracy when it is compared with thetraditional method. The example about SWGECCHE provides an important reference for the scientifically usinggeothermal resource,too.
