摘要:
为得到阻力性能较好的机器鱼壳体结构参数,先通过二维流场仿真确定了壳体轮廓方程,应用ICEM CFD建立了三维流场结构化网格模型,对椭圆加抛物线的线型回转体进行了FLUENT仿真。重点研究了壳体尺寸参数变化对形体阻力的影响。结果表明,椭圆与抛物线外形的壳体行进阻力相对较小; 相同雷诺数下,最大截面直径越大,形体行进阻力越大; 最大截面距前端约一半体长时,形体具有最小行进阻力,并根据仿真结果设计研制了机器鱼壳体外形。
Abstract:
In order to obtain better shell structure parameters for resistance performance of robotic fish, two-dimensional flow field simulation is conducted to determine the shell contour equation, then ICEM CFD are applied to establish a three-dimensional flow field structure of the grid model, and an elliptical parabolic linear slewing FLUENT body is also simulated. Focus of the study is given to the influence of parameters on the size of the shell resistance. The results show that: shells with parabolic or elliptical shape have relatively small resistance; at the same Reynolds value, the greater the maximum cross-sectional diameter, the greater the resistance; with maximum section from the front end of about half the body length, the body has the minimum running resistance. And according to the simulation results of the design of robotic fish shell shape is developed.
