| 摘 要： | 用水模型模拟研究了浸入喷粉过程中气泡与射流两种机制的主要不同之处。在同类研究中第１个引入水中粒子探测器直接测量射流的几何形状，粒子在液体中的穿透和散布以及气体在射流过程中的卷入等，实验表明，喷吹气／固比是决定喷粉过程两种机制的主要因素。

| Abstract: | Simulation experiments were carried out to compare the main differences between bubbling and jetting regimes during submerged powder injection. An Aqueous Particle Sensor (APS) was first used for direct measurements to detect size of the injection plume, particle penetration and dispersion into liquid and gas entrainment in jet flow. The effect of gas and powder flow rates (powder/gas loading ratio) were the main parameters for determining the injection regimes and particle behavior. |
