Numerical investigation on the dynamic placement and recovery of UUV based on dynamic grid technique
In the process of docking between UUV and underwater device,there exists a problem of two-body interfer-ence with strong nonlinear characteristics.In order to find out the change of hydrodynamic force with docking attitude in the process of UUV docking,this paper adopts the dynamic grid technique to carry out the numerical simulation research on dy-namic recovery process of UUV.The influence of UUV motion velocity and attitude on its fluid dynamics and flow struc-tures is systematically analyzed.The research results of current paper can provide technical guidance and theoretical support for subsequent prototype tests.
