【摘要】 用数值计算和实验的方法研究单个裂缝-溶洞中单相流动问题。从流体运动基本方程出发,建立裂缝溶洞之间流动的数学模型,采用投影差分格式求解,得到流体在缝洞模型中流动时流场的分布规律,给出压力和速度的空间分布。数值模拟和实验表明:当溶洞足够大,裂缝到溶洞中流动与“射流”相似。更多还原

【Abstract】 The single-phase flow in fracture and cave is studied on the base of numerical computation and experiment.The numerical model is put forth and calculated through projection method.The distribution law of flow field in fracture and cave is obtained and distribution of pressure and velocity are also given in this paper.Numerical computation and experiment show that the flow from fracture to cave is similar to jet flow if the cave is big enough.更多还原
