The nozzle of the gasifier is simplified. The cold-flow field in the gasifier chamber is studied. The research shows that the chamber has recirculation along the whole length. The particles in the chamber perform a very good flowing characteristics even for the large particles of dp=150μm, and no abrupt change is observed. This is due to the operational pressure is high and the density of the gas is large there. The maximal reflux velocity of both phases, the reflux intensity, the concentrational distribution of particles, and the static pressure loss in the chamber are all related to following factors: the load of gasifier, the concentration of coal-water slurry, the diameter of the coal particle, the distribution ratio of oxygen in the two channels of the nozzle, and the angle of jet in nozzle.

本文对水煤浆气化炉喷嘴进行了简化处理，在此基础上，对气化室内的冷态流动过程进行了研究，发现：整个气化室都处于流动的回流区长度范围以内；水煤浆气化炉中，由于操作压力很高，气相密度很大，所以即使对于dp=150μm的较大煤颗粒，其对流体的跟随特性也很好，没有发生流动特性突跃的现象；两相的最大回流速度、回流强度，颗粒相的浓度分布，以及气化室内的静压力损失等，均与气化炉的负荷、水煤浆浓度、煤粒直径、O2在喷嘴两个流道中的分配比例、以及喷嘴的射流角等参数有关。

To reveal aft end internal flow feature of a solid rocket motor with submerged nozzle, a two dimension cold flow test model with rectangular channel was designed The cold gas simulation was based on geometric similarity and aerodynamic analogy Mean and fluctuating velocity field was measured using phase doppler particle analyzer It showed that the flow separates at upstream of the submerged nozzle and reattaches on the tip of the nozzle nose A relatively steady recirculation zone formed in...

为了揭示含潜入喷管的固体火箭发动机尾部流动特征，按照几何相近和气动相似原则设计了通道为矩形的二维冷流实验模型，利用相位多普勒粒子分析仪对燃烧室尾部气流的时均速度和湍流脉动速度进行了测量。实验结果表明气流在潜入喷管入口上游发生分离，再附点位于喷管前端部外侧，背壁空腔内形成一个较为稳定的回流区，流场的轴向和横向湍流强度都比较大

Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。
