| 摘 要： | 通过水力学模拟实验,研究了湍流控制器结构对中问包内流体流动特性的影响.结果表明:湍流控制器的结构埘巾间包流体流动特性有较大的影响.湍流控制器内腔形状为槽形,顶缘长度为30mm且其底部形状为平底时,流体在中间包内的斤始响应和平均停留时间最长,死区体积分数最小,活塞流与死区体积的比值最大,而且最有利于中问包内的夹杂物上浮去除.同时,相对于湍流控制器的内腔形状和底部形状,其顶缘长度对中间包内的流场影响最大.

| Abstract: | The influence of the configuration of turbulence inhibitor on the characteristics of fluid flow in a tundish is studied through water modeling experiments.The results show that the fluid flow behavior in the tundish is greatly affected by the configuration of turbulence inhibitor.Turbulence inhibitor with grooved shape inside,30 mm in length of its extending lip at the top of the sidewall and flat bottom inside has the best flow field in the tundish.It is propitious to prolong minimum breakthrough time and ... |
