It is shown that the velocity of solid slug equals to 0.51 times gas velocity approximately. As suggested by Barth, The total pressure drop may be Correlated as the sum of pure air pressure drop and the additional pressure drop due to the presence of solid particles.

The pressure drop and solid slug velocity in horizontal pulsed dense phase pneumatic transport are investigated by using PVC powder as transporting material. It is shown that the velocity of solid slug equals to 0.51 times gas velocity approximately. As suggested by Barth, The total pressure drop may be Correlated as the sum of pure air pressure drop and the additional pressure drop due to the presence of solid particles. The frictional coefficient of additional pressure drop related to gas Froude number may be represented by λ_m=3.75F_r~(-1.6). A capacitance probe technique, which has no perturbation of flow condition is successfully used to record the flow pattern of solid slug. After simple treatment of the recorded picture, the velocity of solid slug and related parameters are obtained.

The hydrodynamic problem of the high speed impact between a water slug with curved head and a rigid surface assumes time-dependent inviscous compressible flow of fluid. It is governed by the equation of continuity and momentum for the liquid in cylindrical coordinates with axial symmetry, the isentropic equation of state for water. They are solved numerically by combined Eulerian and Lagrangian approaches, for a non-slip wall condition. The results of numerical calculation are indicated as follows. When the peak pressures are reached, the peak lateral velocities that are more than the impact velocity are reached instantly; the act time is independent of the impact Mach number approximately in lower impact Mach number, the peak pressures and the peak velocities increase along the radial direction outwards, and some experimental evidence supports this result.

曲面头部的水弹高速冲击刚性表面的流体动力学问题,可以归结为无粘性、可压缩的不定常流动问题,受轴向对称园柱座标的连续和动量方程、水的等熵状态方程支配。考虑不可滑移的刚壁边界条件,用欧拉——拉格朗日结合的数值计算方法,进行数值求解。计算结果表明:在压力峰值形成的同时,引起了比冲击速度大得多的侧向速度;在较低的冲击马赫数范围内,作用时间近似地和冲击马赫数无关;压力峰值和测向速度都是沿着径向向外递增,这和实验结果一致。

Because of the characteristic of the mechanics of deformation in cold extrusion,frequently,the main obstacle to limit the degree of deformation depends on the extru-sion pressure which can be endured by the extrusion die used.The allowable extrusionpressure is determined by the quality of die material,the structure of extrusion dieand the desirable tool life.At present,we suggest that the degree of deformation incold extrusion be determined according to the allowable extrusion pressure in therange of 200~250 kg/mm~2.Taking into consideration the influence of technology factors such as the carboncontent of extruded metals,the hardness of slug,the relative thickness of slug andthe profile of the die,according to the suggested isopiestic principle,the authors pre-sents the diagram and the calculating formulae for determining the allowable degree ofdeformation in cold extrusion of ferrous metals.

由于冷挤压的变形力学图形特点,限制黑色金属常用钢材冷挤压变形程度的主要障碍往往首先在于模具所能承受的单位挤压力。模具许用单位挤压力的数值应根据模具材质质量、模具结构特性以及所要求的模具寿命加以决定;许用变形程度亦受到上述各因素的影响。在目前情况下,可按200~250公斤/毫米~2范围的许用单位压力决定许用变形程度。作者根据所提出的“等压”原则,给出了黑色金属冷挤压工序许用变形程度的图线与计算公式,其中考虑了挤压钢材的含碳量、毛坯硬度、毛坯相对高度以及模具几何形状各个因素的影响。
