部分滑移边界条件下自由液面流动问题研究

STUDY OF FREE SURFACE FLOW WITH PARTIALLY-SLIP BOUNDARY

  • 摘要: 数值方法进行相关问题的研究就以圆柱形储液罐为例, 考虑部分滑移边界条件, 对所得的高度非线性微分方程进行了数值求解, 讨论了贮液腔体内液面接触线和液体高度线, 及部分滑移条件对流体层微观半径的影响; 所得结论对自由液面晃动问题数值研究中的边界条件处理有参考意义.

     

    Abstract: The researches on sloshing of the free surface flow in containerscarrying liquid are of theoretical and practical significance. Numericalsolutions often involve some approximations of the boundarycondition, when considering the wide-range movement or the nonlinearityof the free surface flow. In this paper, under partial slip boundary conditions,the high-order nonlinear differential equations of a cylinder-shapedpartially filled liquid container are numerically solved. Theinfluences of the contact line and the fluid height of liquid and the partial slipboundary conditions on the macroscopic radius of the fluid layer are discussed. The results may serve a reference for treating similar boundaryconditions of free surface flow for partially filled liquid carryingcontainers.
