摘　　要：运用Fluent软件对实验中自行设计的化学复合镀槽内的流场进行数值模拟，用Gambit建立流体区域的实体模型，采用RNG型k-ε湍流模型及多重参考系法（MRF）处理搅拌区域。选取了多种搅拌转速进行计算模拟，并对计算结果进行定性检验分析。结果表明，计算所选的模型能较准确地反应镀槽内的速度场，在90～110r／min时，镀槽内的速度场最均匀。模拟结果将为实验研究提供指导，对提高复合镀层的表面形貌和组织性能具有一定的参考价值。Digital simulation of flow field in the self-designed electroless composite plating bath is carried out using software FLUENT. The entity model of fluid region is established by GAMBIT and the stirring region is processed using RNG k-ε turbulent flow model and multi-reference frame method （MRF）. Computational simulations are carried out under different stirring speeds and the results are verified experimentally, that the adopted model could simulate the flow field in the bath accurately, and that the speed field in the bath is more uniform when the stirring speed is between 90 and 110rpm. The simulation results provide a guide for us to design experimental parameters and are helpful to obtain expected structure and properties of the electroless coating.
