Abstract	利用复杂流动相似准数敏感性分析的方法,从理论公式及数值分析出发,分别将该方法应用于Wigley船模阻力分析、剪切流中对称Joukowsky翼型的升力和力矩系数分析,以及脉冲管制冷机内部交变流动与换热的分析中.仔细比较了Re, Fr, Sr, Ma等无量纲参数对不同目标函数的敏感性,定量地得到了上述无量纲参数的敏感区间,并将数值结果与实验结果进行了比较,为相关工程应用提供了依据
Other Abstract	Based on the theoretical formula and numerical simulation,the sensitivity analysis of scaling law are performed in complex flows,such as the resistance of Wigley ship,the lift of symmetrical Joukowski airfoil in shear flow,and the oscillating flow and heat transfer in Pulse-Tube Cryocooler(PTC).The computational results are well compared with those of experiments.The sensitivity analysis facilitates us to identify which factors in terms of dimensionless form are more important and should be paid more attention to.These conclusions can be referred to in engineering applications
