用格子Boltzmann方法建立了椭圆柱体的二维动力学模型 ,利用所建立的模型 ,数值模拟了牛顿流体中不同形状的椭圆柱体在相同初始条件下的运动和同一椭圆柱体在不同初始条件下的运动 ,并通过比较相同条件下圆柱体的运动 ,讨论了椭圆柱体二维运动的特征 ,得到了一些有意义的结果 . Lattice Boltzmann method was used to establish the two-dimensional dynamic model of elliptic cylinder. Using the established model, the numerical simulation of the motion of elliptic cylinders of different shapes in Newtonian fluid under the same initial conditions and the same initial conditions of elliptic cylinder under different initial conditions By comparing the movement of the cylinder under the same conditions, the characteristics of the two-dimensional motion of the elliptic cylinder are discussed and some meaningful results are obtained.
