The mixing power and circulation characteristics of Newtonian fluid and pseudoplastic fluid were measured in a φ300mm organic glass vessel,by using anchor and tri-leaf impeller,anchor and inner-outer screw,orthogonal twi-stratm triangle blades and single screw,orthogonal twi-stratum triangle blades and inner-outer screw types of combined agitators.

为使聚合釜内搅拌介质在湍流、过渡流及层流域都能达到良好的混合,对锚-三叶推进器、锚-内外单螺带、正交双层三角-单螺带、正交双层三角-内外单螺带等4种组合搅拌器,于φ300mm的有机玻璃釜中,测定了在牛顿流体和假塑性流体中的搅拌功率和循环特性。

On the basis of analyzing the theory of the modeling of the propeller surface, this paper transforms the section data given by design to the data in Descartes coordinates. Interpolates the section data to get enough data and fits the blade surface with the least square method. A perfect C2 blade surface can be obtained by adjusting the deviation weight and fairing weight. According to the cylinder rough, two rough cut methods are preferred.

本论文在深入分析螺旋曲面成型原理的基础上,将设计时给定的叶曲面的切面数据转化为笛卡尔坐标系中的坐标,利用B样条方法对截面数据点插值并加密,得到足够的数据点,进而利用最小二乘法拟合出叶曲面,通过调整偏离权和光顺权得到了理想的二阶连续的叶曲面。

A maneuvering mathematical model for Controllable-Pitch Propeller ships with three degrees of freedom is established according to separate modeling theory. Based on Netherlands Ship Model Basin\'s open-water tests, CPP thrust coefficients and torque coefficients in four-quadrant with different pitch ratio of screw and different types of CPP are obtained by using Akima interpolation. Therefore, CPP thrusts and torques are obtained.

基于船舶操纵性分离建模理论,采用荷兰船模试验水池B系列螺旋的敞水试验结果,利用Akima插值获得了不同类型的调距在不同螺距比下的四象限推力系数和扭矩系数,求得调距的推力和扭矩,建立了调距船舶的平面运动数学模型。
