To describe the characteristic of turbulence as 3D transient phenomenon with random fluctuations which is highly nonlinear, turbulence modeling ranging from approximate to highly rigorous was proposed.
为了准确描述湍流三维非稳态随机波动这一高度非线性的特性,简述湍流物理现象的特点,引出基于不同角度建模的湍流模型,在理论上对大涡模拟进行分析,并运用并行计算机、FLUENT6。
The statistical method focuses on considering the distillate of soil variability by separating the certain component that can be depicted by the function of trend and the disturbance component that can be characterized by the random fluctuation efficiently.
结果表明:土性指标变异性并非土体分层后层与层之间土性指标的差异,而是层内土性点与点之间的空间变异;相对于传统随机变量的建模方法,这种空间变异性用随机场理论建模更加科学合理;随机场理论用空间趋势函数和随机波动分量分别表征土性指标的确定性部分和随机扰动部分,通过去趋势化处理,可把握土性参数不确定性的核心;实例分析显示,本文提出的方法可更加精确地了解土性参数的不确定性,为可靠性理念在实际工程中的应用提供有利的途径。
