摘要
采用SIMPLE算法、S-A湍流模型求解了三维不可压雷诺平均N-S方程,数值模拟了绕飞艇的低速不可压粘性流动,计算了不同艇身外形的阻力特性。本文方法计算结果与实验结果或其他文献的计算结果符合良好,可以用于飞艇的气动特性计算。通过对6个不同外形的相同体积飞艇阻力特性计算,得到了最佳艇身外形,表明本文方法可以用于艇身外形的选型设计。
In this paper, we utilize SIMPLE method and S -A turbulent model to solve the three -dimensional incompressible Reynolds - averaged N - S equation. The low speed incompressible viscous flow around airships is numerically simulated and the drag characteristics of different shapes are calculated. The results show that, the method of this paper can be applied to calculate the aerodynamic characteristics of airship. By study of six different airships＇drag characteristics, an optimized shape is determined.
