流体不稳定性现象广泛存在于自然界和工程应用领域,属于诸多学科的交叉研究对象,如流体力学、海洋学、天体物理、大气物理、地质学、航空航天学等。流体不稳定性往往包括典型的可压缩效应、非平衡效应、多尺度效应、非线性效应等。尤其在其演化后期,往往会导致湍流现象的发生,并在流体内部形成复杂的形态结构。如何有效模拟和准确预测流体不稳定性的全时空、全物理的演化,一直是国内外的开放课题。为此,我们基于非平衡统计物理学,构建了准确、稳定、高效的离散玻尔兹曼方法,模拟研究了流体不稳性的演化过程,从微介观层次分析了复杂流体的宏观动力学行为,并从动理学角度探讨了流体不稳定系统的机制特征。![](https://public.fangzhenxiu.com/fixComment/commentContent/imgs/1660047131243_db98qq.jpg?imageView2/0)
