摘要:Computational fluid dynamics (CFD) has been widely used in the field of marine engineering recent years. In this work, the free falling process and working posture of gravity sampler have been studied using OpenFOAM. The overset grids have been used to simulate the movement of the sampler in the flow field. Main works are as follows: (1) verifying the accuracy of the overset grid method; (2) establishing a numerical model using the Newmark method to analyze the responses of sampler vertical and slant drop; (3) investigating the relationship among the deflection angle, falling speed and sampling rate of sampler. Finally, the best fall distance of GPS-01 sampler has been recommended in combination with the falling velocity and the initial falling angle.
