摘要
应用有限元软件ANSYS,以与采水器外壳接触的周围水域为研究区域,计算其总阻力系数及最大运动速度。采用相同的数值方法计算了圆球总阻力系数,计算结果与经典实验结论吻合良好,证明了该数值方法的准确性。利用ANSYS软件计算预报采水器或其他类似的海洋仪器在流体中的阻力系数,可指导其尺寸参数设计。
Taking the water around the sampler as research area, FEM software, ANSYS, is utilized to calculate the sampler＇s resistance coefficient and its maximum rising speed. Meanwhile, the same numerical calculation method is employed to calculate the ball＇s total resistance coefficient, and the results agree with existed experimental data quite well. The ANSYS is able to calculate and report the resistance coefficient of the sampler or other marine instruments to instruct the instrument design.
