针对薄板坯连铸结晶器中钢液的紊流流动特征，利用商业软件CFX4．2，建立了一个三维有限差分模型，计算这一限定空间射流的紊流时均场，并采用均相流模型，模拟了结晶器内钢液液面形状及速度场．通过计算，分析了浸入式水口形状、拉速等工艺参数对薄板坯连铸结晶器流场的影响，同时，研究了结晶器出口处速度分布对结晶器内钢液流动的影响．
Aiming at the turbulent flow characteristics of molten steel in thin slab continuous casting mold, a three-dimensional finite difference model was established by using commercial software CFX4.2 to calculate the turbulent mean field of the confined space jet. The homogeneous flow model , Which simulates the shape and velocity field of molten steel in the mold. Through the calculation, the influence of submerged nozzle shape, pulling speed and other parameters on the flow field of thin slab continuous casting mold was analyzed. At the same time, the influence of velocity distribution at the exit of mold on the flow of molten steel in mold was analyzed.
