| 摘 要： | 考虑到大部分铸件充型过程均处于湍流状态 ,将工程湍流模式用于液态金属的流动和传热计算 ,并与层流计算结果、基准试验以及铜型压缩机灰铁铸件试验结果进行了对比 ,分析了计算结果之间产生差异的主要原因 .简要介绍了相应的数值算法以及在流体自由表面处理方法上与传统方法的不同之处 ,对铸件充型之后的凝固过程也进行了模拟计算且与现场试验作了对比 .

| Abstract: | Considering the turbolent mould filling process for large castings, applies the engineering turbulent mode to the liquid metal flow and heat transfer calculations, and compares them with the result of laminar flow calculation, and the results of reference test and copper mould compressor grey iron casting test, and investigates the major causes for the difference between calculation results, berefs the corresponding numeric calculation, the difference between the free surface treatment of fluid and the traditional one, runs simulation calculation for the solidification process after mould filling and compares it with in stitu test. |
