摘要
本文论述了非线性拖曳力的各种线性化方法,导出了非线性拖电力谱零阶矩和二阶矩的直接计算公式,并根据谱的零阶矩和二阶矩,提出了评价线性化方法的判定方法。最后,对Rodenbusch方法和作者使用的方法计算的线性谱做了实际计算。计算表明,由作者方法计算的零阶和二阶拖曳力谱谱矩更接近于原拖曳力谱谱矩。
Various methods of linearization of nonlinear drag force are introduced in this paper.The methods for direct calculation of zero and second order moment of nonlinear drag force have been developed.A method of evaluation of the effectiveness of linearization has been given.The comparison between Rodenbusch's and author's methods have been made.The results of zero and second order moment of linearized drag force spectrum from author's method is more closer to the original nonlinearized drag force spectrum.
