【摘要】 了解管道出口处气固两相流中颗粒速度的大小,对研究喷射冶金过程具有重要意义。在第一阶段建立数学模型和进行理论计算的基础上,作者对等截面管道中气固两相流的颗粒出口速度进行了初步的实验研究。由求解数学模型所得颗粒出口速度与用激光测速仪实测颗粒出口速度的比较可见,所建立的数学模型基本上是正确的。更多还原

【Abstract】 It is very important to the study of injection metallurgy to understand the value of particle velocities of gas-particle flows at the outlet of the duct.Elementary experimental investigation on terminal particle velocities of gas-particle flows in a constant-section duct was made based on the established mathematical model and theoritical caiculation made in the first stage.By comparing the particle velocities at the outlet obtained by solving the mathematical model with the particle velocities at the outlet measured by a laser anemometer,it was shown that the model was basically correct.更多还原
