二维流冰消融数学模型
Two dimensional numerical model of turbulent flow and ice melting
【摘要】 本文采用水深平均kε双方程紊流模型与流冰拟流体模型首次推出了适合于天然实际工程水域复杂条件的紊流流冰消融数学模型.模型还利用离散型动态边界拟合坐标变换系统以适应天然水域的不规则边界与复杂流态,对天然流场中常出现的露滩、断流、动态水边界及几何曲率影响等特殊数值计算问题的处理颇有实效,具有较大的实用价值.本文以丹东电厂温排水缓冰工程为例验证了数学模型.
【Abstract】 Using the depth averaged k ε turbulence equations, this paper develops a two dimensional numerical model of turbulent flow and ice melting fields for natural water areas such as river, estuary and coastal water. Particular emphasis is put upon simulating the ice flowing and melting process in turbulent fluid flow under complex geometric and hydraulic conditions which can be well treated with the discretized moving boundary fitted coordinate system. The application shows that the model is very practical and efficient in solving the turbulent ice flowing and melting problem.
