摘　　要：借助CFD理论与技术和商业软件Fluent对YD生物公司的650L搅拌式细胞反应器挡板对流场的影响进行了数值模拟与分析。针对直径D=800mm,液位高度为h=1000mm,推进式桨叶直径为Φ=350mm,桨叶距罐底高度H=355mm,转速n=60rpm的搅拌式细胞反应器,通过改变反应器所加装挡板的数量,运用Realizable k-ε湍流计算模型模拟分析在罐体壁均布挡板数量分别为0、2、3、4、5、6等六种情况下的流场,并对模拟结果分析比较;发现挡板对流场的影响明显,均布5块挡板时流场整体轴流性最好。Undre the help of CFD theory and technology and the commercial software Fluent,we take the study on the impact of flow field between number of the baffle.For a diameter D=800,the height of the liquid level h=1000mm,diameter of the propeller blades Φ=350mm,the blades from the bottom of the tank height H=355mm,baldes speed n=60rpm,the stirred reactor,by changing the number of the baffles and using the Realizable k-εmodle to find the difference of flow field of the baffle number such as 0、2、3、4、5and 6.And we also take some comparation with the simulation results.It is found that the baffle take significantly effect in the flow field of the stirred cell-reactor;when installing 5baffles,the overall flow field of the reactor is going very well,and this is the best case.
