Abstract沉积层中水合物热分解是一个含有水合物相变的热传导过程,相变界面的演化过程是水合物分解规律及相关灾害分析的最基本问题。文中在试验观测和分析实际物理过程的基础上,建立了水合物沉积层中混相-多相变阵面-多区域的热传导理论模型,并针对轴对称问题进行了系列数值模拟;模型试验测定了四氢呋喃水合物沉积物中不同热源温度下水合物相变阵面的演化过程。通过对比,水合物分解相变阵面扩展的数值与试验结果吻合较好。
Other AbstractThermal conduction and phase transformation are essential physical-chemical processes in the dissociation of gas hydrate deposit.The evolution of thermal conduction and dissociation front is the most fundamental scientific problem in the investigation of gas hydrate dissociation and related hazards.An axial symmetric theoretical model is presented based on experimental observations and comprehensive analysis of the physical process.A numerical method is obtained.The THF hydrate phase transformation fronts i…
