| 英文摘要 | Plasma cutting arc characteristics are investigated for different turbulence models, i.e. the Reynolds stress model (RSM), the k-epsilon model and its variants, the renormalization group (RNG) k-epsilon model, the RNG k-epsilon model taking into account the low Reynolds number effect and the realizable k-epsilon model. The results of the RSM and the RNG k-epsilon model taking into account the low Reynolds number effect are in reasonable agreement with experiment. They both predict very close voltage, shock wave location and temperature variation along the axis to experiment. On the other hand, the other three models overestimate the turbulence effects and predict much lower velocity and temperature, especially the standard k-epsilon model, which predicts that the temperature is about 10 000K lower than the experiment in certain plasma jet regions. |
