【摘要】：肥皂泡体作为非线性流体,对于外界的作用有着极其复杂的非线性响应。研究肥皂泡体中运动物体的动力学行为能够解释和解决生产和生活中的很多相关问题。通过理论建模、实验设计和数值模拟对于小而轻且与肥皂泡大小相差不大的球体在与肥皂泡体中的运动过程进行研究。首先从统计力学的系综角度给出了三维肥皂泡体动力学行为的理论解释,再从实验上验证了在重力场作用下,小球在肥皂泡中的动力学行为关系式,具有普遍性。
[Abstract]:As a nonlinear fluid, the soap bubble has extremely complex nonlinear response to the external action. Studying the dynamic behavior of moving objects in soap bubble can explain and solve many related problems in production and life. Through theoretical modeling, experimental design and numerical simulation, the movement process of small and light spheres with little difference with the size of soap bubbles was studied. In this paper, the theoretical explanation of dynamic behavior of three dimensional soap bubble is given from the angle of ensemble of statistical mechanics, and the equation of dynamic behavior of small ball in soap bubble under the action of gravity field is proved to be universal.
