摘　　要：数值模拟研究Stokes流动中的液滴变形问题。采用边界积分方法计算液滴表面的运动,建立在网格能量最小化基础上的自适应表面离散及网格局部重建方法以准确的分辨出变形液滴的形状,并将数值模拟结果与实验结果进行了比较,模拟结果表明,本方法能够较好的模拟液滴变形的动力学特性。Numerical simulation of drop deformation in stokes flow has been studied. Boundary integral method is used to capture the evolving surface. The surface discretization is fully adaptive through minimization of mesh energy with local restructuring operations, which provides accurate resolution of the deformed drop shapes. There have a good agreement between the simulation results and the experiment data, which means this proposed method can be used to predict drop deformation well.
