Solar Underwater Glider Hydrodynamic Calculation

In this paper, we study Solar Underwater Glider, is a new kind of underwater vehicle, and carry its own solar photovoltaic power generation system can provide power for long endurance. Solar Underwater Glider has a wide scope of operation, long continuous operation time, low energy consumption, etc. The hydrodynamic coefficients of.underwater vehicle is one of the important indicators to measure underwater vehicle handling performance, therefore, to obtain the hydrodynamic coefficients of Underwater Solar Glider is a great significance.Firstly, this article provided by ANSYS CFX fluid analysis software has simulated low-speed wind tunnel tests of Solar Underwater Glider, and the related location force hydrodynamic data to MATLAB nonlinear fitting, get the related position force to hydrodynamic coefficients, and through the low-speed wind tunnel tests numerical simulations of post-processing, analyzes the part conditions of surface pressure distribution and change situations, the change of flow field and its surrounding waters.Secondly, this paper simulated arm tank tests of Solar Underwater Glider, and the related rotating force and bonding force hydrodynamic data to MATLAB nonlinear fitting, get the related rotary force and bonding force hydrodynamic coefficients, and through the arms tank tests numerical simulations of post-processing, analyzes the part conditions of surface pressure distribution and change situations, the change of flow field and its surrounding waters.Finally, the article adopts flow field of Solar Underwater Glider in water adding additional momentum source, the method of Solar Underwater Glider unsteady tests have been carried out numerical simulations of Solar Underwater Glider to harvest energy inertia type of hydrodynamic, and carries on the hydrodynamic data obtained Fourier transform, obtained the relevant additional quality.
