摘要
利用采用高阶有限差分的迎风格式,从探讨网格模型与计算结果之间的关系入手,通过数值计算模拟了新月形冰型的覆冰导线模型在不同攻角下的阻力系数、升力系数以及斯特鲁哈尔系数的变化规律,并与高雷诺数试验结果进行了对照分析。在一定程度上,数值结果反映了新月形冰型的覆冰导线模型气动力特性。
Higher order finite difference method with upwind difference scheme has been used in this paper. From the study of the relation between mesh model to calculation result, it calculates the drag coefficients, lift coefficients and the variation rules of Strouhal numbers at higher Reynolds number for the crescent shape iced conductor model at various angles of attack. And then it compares the result of numerical simulations with the result of the experiments at high Reynolds numbers. To some degree, the numerical result reflects some rules of the static aerodynamic characteristics of iced conductors.
