| 中文摘要: |
| 采用FLUENT软件，选择标准k-ε模型、RNG k-ε模型、低雷诺k-ε模型(Abe-Kondoh- Nagan)对停滞板燃烧器内冷态流场进行数值模拟，然后将模拟结果和实验结果进行比较。结果表明，RNG k-ε模型和AKN(Abe-Kondoh-Nagan)模型得到的结果与实验结果比较接近。用RNG k-ε模型和Abe-Kondoh-Nagan模型对停滞板燃烧器的预混燃烧进行数值模拟，通过与实验结果的比较，评价了两种湍流模型对停滞板预混燃烧的数值预测能力。 |
| 英文摘要: |
| Using FLUENT, a numerical simulation of the cold flow in the stagnation-plate burner was carried out with the standard k-εmodel, RNG k-ε model and the model of Abe-Kondoh-Nagano (AKN model). The results were then compared with experimental data. It is indicated that the simulation results from RNG k-ε model and AKN model are in better agreement with the experimental data. Moreover, the RNG k-ε model and AKN model were used to simulate the premixed combustion of the stagnation-plate burner. By comparison with the experimental data, the numerical predictive abilities of the two turbulence models on premixed combustion of the stagnation-plate burner were assessed. |
