| 摘 要： | 地层储能技术是实现能源可再生和清洁高效利用的有效途径之一,在考虑岩土含湿的基础上,建立了湿岩土体的传热模型,着重分析了在瞬时热源作用下,地下温岩土温度场的演化规律,旨在研究岩土含湿率对其传热特性的影响.分析和计算结果表明,在岩土体临界含湿范围内,岩土含湿率越大,其热传导能力越强,岩土热响应时间越短,越有利于地层中热量的...

| Abstract: | Underground thermal energy storage is an approach that can makes the reuse and efficient utilization of the energy sources to be realized.The heat transfer model of wet soil was proposed considering the dampness characteristic of soil.The temperature evolvement rule of underground wet soil was analyzed to study the impact of soil including water on the heat transfer characteristic based on the heat source theory.The results show that the soil contains the more water,the heat conduction ability of soil becom... |
