Numerical simulation of hydrodynamic characteristics of underwater snake-like robot

摘要

The snake-like robot underwater motion performance is analyzed in computational fluid dynamics method. The mathematical and numerical model of the robot with fluid turbulent motion in flow field is presented. The positive pressure of the flow field around robot head is rendered as streamlined and its tail presents a very strong vortex phenomenon. The configuration of the robot should be designed as streamline structure to improve its motion performance.
