摘　　要：浸入式水口内吸附杆结构对夹杂物运动行为有直接影响,吸附杆壁面凹槽类型不同,夹杂物在其内部碰撞聚集的效果不同。通过水模拟试验,研究了浸入式水口内吸附杆凹槽类型对夹杂物碰撞聚集的影响。结果表明,夹杂物粒子在矩型凹槽内碰撞、聚集区主要集中在凹槽上部,在钩型凹槽内碰撞、聚集区主要集中在凹槽中下部。矩型凹槽较钩型凹槽更有利于夹杂物的聚集,即矩形凹槽内的夹杂物更容易与壁面碰撞,凹槽吸附夹杂物的能力更强。The structure of the adsorption rod in submerged nozzle has a direct influence on the motion behavior of inclusions,the types of grooves on the wall of the adsorption rod are different,so the effects of collisions and aggregation among inclusions are different inside the groove.The effectsof groove types on the collision and aggregation among inclusions in submerged entry nozzle were researched by water simulation experiment.The results showed that the collision and aggregation area between the inclusion particles and the rectangular groove were concentrated mainly on the upper part of the groove,and the collision and aggregation region of the groove with the hook type was concentrated in the middle and lower part of the groove.The rectangular groove has better aggregation ability than the hook groove,namely,the inclusions in the rectangular groove were easier to collide with the wall,and the ability to adsorb the inclusion was stronger.
