为了研究几何参数对三维仿生运动翼推进性能的影响
基于IB-LBM算法开发了可在天河2号超级计算机上运行的大规模并行求解器。实现过程包括用浸入边界法在翼型表面构造力函数
并通过插值函数将翼型表面的力函数分散到周围流体网格点
然后通过格子波尔兹曼方法进行流体计算
更新速度场。以椭球翼、平板翼、NACA0012翼、长方体翼为研究对象
系统研究了仿生翼的几何形状对推力系数与涡系结构的影响。研究表明:椭球翼表面的涡系结构饱满且距离翼型表面最近
其推进性能最好; NACA0012翼和平板翼的涡系结构类似
推进性能相近; 长方体翼由于钝体效应导致涡系结构细小且距离翼型表面较远
其推进性能最差。研究结果表明
在仿生飞行器设计中
应避免采用类似于长方体外形的钝体仿生翼
椭球翼推进性能最佳
但是由于椭球型质量分布导致对仿生飞行器连接部位质量要求较高
可采用推进性能相近的平板翼。
To study the influence of geometric parameters on the propulsion performance of three-dimensional bionic motion wings
a general large-scale solver based on IB-LBM algorithm for Tianhe-II supercomputer is developed. To implement this process
the immersed boundary method is used to construct a force function on the surface of the wing. Then the force function is spread to the neighbor fluid mesh with interpolation function. The lattice Boltzmann method is used to perform fluid computation and update the velocity field. Four different wings
i.e.
ellipsoidal wing
plate wing
NACA0012 wing and cuboid wing
are investigated to explore how the geometric shapes of the wings influence the thrust coefficient and vortex structure. The numerical results show that the vortex induced by the ellipsoidal wing is fully structured and close to the surface of the wing
so its propulsion performance is best. The vortex structures of NACA0012 wing and plate wing are similar
and hence have similar propulsion performance. The vortex structure of cuboid wing
however
is small and far from the wing surface
leading to a worst propulsion performance. So
in design of bionic airplane
the cuboid wing should be excluded. Although the performance of ellipsoidal wing is best
it requires a high-quality mass distribution in connection parts
so the plate wing would be a proper choice as a result of tradeoff.
