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
With the goal of studying the fine prediction model of two-phase stratified flow in water environment, the theories and methods of fine simulation of two-phase turbulence are extensively studied. The multi-fluid model in the Eulerian coordinate system is used to describe the motion of each phase uniformly. The turbulent transport observations of two-phase bisection and the law of inter-earth interaction are simulated respectively. Two-phase stratified flow The model numerically simulates two-phase turbulent flow with buoyancy and density stratification. The calculation results correctly reflect the characteristics of stratification and turbulence, which is in good agreement with the measured data
