摘要
基于商业CFD软件FLUENT定常N-S方程,在不同计算资源下数值模拟了某标准导弹在不同飞行马赫数、滚转速度和迎角时的滚转特性,并与AEDC报告实验结果进行了对比。计算结果验证了定常算法数值模拟滚转阻尼系数的可行性及其在不同计算资源下计算精度的可优化性,而且定常算法与非定常计算相比消耗更少的计算资源。
Based on steady N-S equation of the merchant CFD software FLUENT,numerical simulations of a kind of standard missile model＇s roll-damping coefficient were taken under different Mach numbers,rotational speeds and attack of angles,after compared with empirical results of the AEDC papers,though the steady method is simpler than unsteady one,but the feasibility,superiority and the calculation resource requirements got certification.
