德士古气化炉冷态流场测试

Measurement of Flow-Field for Cold-Flow Model on Texaco Gasifier

摘要: 在出口端结构、尺寸各异的六种有机玻璃容器(φ320×8mm,长为1182mm、1680mm)中,用激光多普勒测速仪,测定了不同射流量时的轴向速度分布,并计算了回流量、涡眼位置以及回流区的起止轴向位置。得到了筒体长度、直径、出口结构以及射流量对速度分布和回流量的影响结果,从而揭示出德士古气化炉内的流动状况,认为德士古气化炉中流场是影响化学反应结果的重要因素。

Abstract: The axial and radial profiles at various jetting velocities in plexiglass vesseles of different constructions were measured by Lasser Doppler Anemometry. The position of recirculation eye, the recirculation flow and the axial region of recirculation were calculated.
