Study on Influence of Net Mesh Shape on Deformation of Cylindrical Mesh
The deformation of the mesh in the current is crucial to the fish culture space.Studying the deformation of mesh shape on net coat can improve the performance of net coat better.The accuracy of the numerical model is verified by experiments by using the centralized mass model and establishing the motion control equation of the flexible mesh.Taking a cylindrical mesh garment as an example,the influence of mesh shape on mesh deformation was studied by numerical simulation under different mesh shapes and different flow rates.The results show that the horizontal displacement of the front point at the bottom of the square mesh is larger than that of the back point,and the vertical displacement of the front point is smaller than that of the back point,while that of the regular hexagonal mesh is opposite.At the flow rate of 0.3 m/s,the volume residual coefficient of hexagonal mesh is 8.4%more than that of square mesh.The volume loss of hexagonal mesh is lower than that of square mesh mesh,and the deformation of mesh mesh is improved.
