After the discussion of the algorithm of complexity parameters , lyapunov exponent and apen , the pressure fluctuation in fluidized beds is analyzed quantitatively . the effect of different operating conditions , such as variant gas superficial velocities , axial positions and static bed heights , is discussed 在讨论复杂性参数、 lyapunov指数、近似熵的算法基础上，对流化床压力脉动进行定量分析，讨论了表观气速、轴向位置、静床高等不同操作条件对混沌特征参数的影响及其对应的动力学规律。
Furthermore , we employ iteration and predictor - corrector - approach to solve the nonlinear equations in order to implement the marching procedure . we investigate detailedly the process of the c - type instability for nonparallel boundary layers with three - dimensional disturbances . by investigating the nonparallel boundary layers of three - dimensional body , we 文中通过对三维物体的非平行边界层稳定性的研究,确定最不稳定波的扰动参数和最易失稳的流向、展向位置;对三维扰动的非平行非线性边界层稳定性的研究,得到更精确的扰动放大因子值。
Three kinds of trapezoid , delta and airfoil shaped vortex generators are designed based on traditional , sub boundary layer and micro - vortex generators conceptual design , to study the influence of the shape , height , aspect ratio , chordwise position , spanwise position and direction angles of vortex generators on boundary layer separation control ( 5 )综合分析研究了涡流发生器的工作原理和设计原则。根据国内外资料，研究了涡流发生器形状、高度、展弦比、尖削比、弦向位置、展向位置和方位角等因素对附面层分离控制效果的影响。
