In this paper , the two - phase flow behaviors of gas - solid circulating fluidized bed have been first studied by analysing experimental data . then , based on fractal theory wavelet package analysis ( wpa ) de - noising method was used to denoise solids concentration and pressure fluctuation signals . the solids concentration signals have also been investigated by wavelet multi - resolution analysis and wavelet package decompose , contributed to disclose the non - uniform flow structures of gas - solids phase 然后将基于分形理论的小波包消噪方法用于颗粒浓度和压力波动去噪，并对气固流化床中的颗粒浓度信号进行了小波多分辨分析和小波包多尺度分解，从新角度揭示了气固流态化系统的非均匀气固两相流动结构。
When the rotation has the same direction with the axial velocity , the effect of rotation enforces the intensity of secondary flow and the heat convection , the friction factor and the nusselt number increases as f increase ; when the rotation has the opposite direction with the axial velocity , the flow structure becomes more complicated , for f = 1 . 2 , the complicated structure of secondary flow generates , the friction facior and nusselt number almost has the same value of stationary straight pipe 当旋转方向和主流方向相同时，旋转的作用加强了二次流的强度，使得管道摩擦系数变大，管道换热效果增强；当旋转方向和主流方向相反时，管道内流动结构变化十分明显， f - 1 . 2时，流动结构最为复杂，摩擦系数降至最低，换热效果最弱。

Based on the review , the fluid flow and heat transfer in the curved circular and rectangular pipes have been researched by employing perturbation method and numerical simulation with a physical model under the rotational orthogonal curvilinear coordinate in a rotating curvilinear pipe with multi - parameters . we firstly analyzed the fully developed fluid flow and heat transfer , mixed convection heat transfer , the development of flow and heat transfer in the inlet in different cross section ( circular , elliptical , annular and rectangular crossection ) . the variations of the secondary flow , axial velocity , distribution of temperature , the friction force on the wall , the ratio of friction factor as well as the nusselt number with different dimensionless parameters had been examined in detailed 本文在总结和分析了一个世纪以来有关曲线管道流动和换热特性的研究成果的基础上，以旋转正交曲线坐标系统下的多参数旋转螺旋管道中的对流传热为物理模型，通过摄动方法和有限体积法，首次对各种截面(圆截面、椭圆截面、环形截面、矩形截面)旋转曲线管道内充分发展流动的流动结构和传热特性(包括耦合对流传热特性)以及旋转曲线管道开口段发展流动的流动结构和换热特性进行了系统的数值模拟和理论分析，详细讨论了各种无量纲参数对管道内轴向速度分布、二次流结构、温度分布、壁面摩擦力、摩擦系数比以及管道nusselt数的影响，获得了若干创新性成果。
A two - dimensional double diffusive laminar natural convection in rectangular enclosure is detailed analyzed . the results show that when the thermal and solutal buoyancies aid each other , the airflow consists of one main cellular structure and is steady , regardless of the relative strength variation between the heat and pollutant sources . there are multiple flow structures , however , according to the relative strength when the buoyancies opposing each other 模拟结果表明双扩散自然对流系统的空气流动与传热传质特性完全是由离散热源与污染源浮升力之间的相互作用关系诀定的：当离散热源与污染源浮升力协同作用时，自然对流呈比较稳定的单一流动结构；而当热源与污染源浮升力对抗作用时，自然对流系统随它们之间强度变化呈现出多种流动状态。
