| 摘 要： | 以研究水环境两相分层流精细预报模型为目标，广泛地涉及了两相湍流精细模拟的理论和方法。用Eulerian坐标系中多流体模型统一描述两相各自的运动，并分别对两相本分的湍流输运观作以及地相间互作规律进计模拟，建立了水环境两相分层流的双流体模型对包含有浮力和密度分层的两相湍流进行了数值模拟，计算结正确地反映了分层及紊动特征，与实测结果吻合较好

| Abstract: | The two-fluid model of stratified turbulent two-phase flow in aquatic environment is developed in this paper.The motion of each phase is described by a unified multi-fluid model in an Eulerian coordinate system.The laws ofturbulent transportation for each phase and the restriction of each other between the two phases are completely simulated.The complex two-phase turbulence with strong buoyancy effects is selected to examine numerically.The extensiveexperimental data obtained in stratified flow are used here. Comparison of the results of numerical simulation with theexperimental data is conducted.It has shown that the results of numerical simulation are satisfactory. |
