利用Fluent仿真分析波浪滑翔器的水动力性能

Simulative Analysis of the Hydrodynamic Performances of Wave Gliders Using Fluent

针对波浪滑翔器前向速度与垂向牵引速度之间的关系进行了仿真研究,分析了在不同牵引速度下波浪滑翔器所受的前向力和前进速度并给出了具体的关系曲线。通过Fluent仿真软件进行编译,使滑翔器翼板绕转轴在0°~90°范围内运动,得到翼板在不同波浪流下的转矩系数CM进而得到转矩M,将转矩M与弹簧相对于转轴产生的力矩相比较,得到翼板平衡时的升角,然后对翼板进行受力分析,计算出翼板所受前向力以及前向速度。仿真结果显示,垂向牵引速度越大,设备所受前向力和前进速度越大。

This paper focuses on the simulative study of the relationship between the forward speed and vertical traction speed of the glider. The fro-ward forces and forward speeds of the wave glider at different traction speeds are analyzed to derive the specific relationship curve. The glider wing is compiled by the Fluent simulation software to move around the axis in the range of 0^-90~ to obtain the torque coefficient CM of the wing under different wave currents before gaining the torque M which is then compared to the torque generated by spring relative to the rotation axis to get the angle of elevation when the wings are balanced. Then the force analysis of the wing plate is performed to calculate the forward force and forward speed of the wing plate. Simulation results show that the higher the vertical traction speed, the greater the forward force and forward speed of the equipment.
