| 摘 要： | 利用FLUENT 6.0流体动力学计算软件对轴对称回转体的自然空化现象进行了数值模拟,得到了不同头型和不同空化数下的回转体周围空泡绕流流场和体积分数分布.计算结果与其他研究人员的计算与试验结果比较吻合,说明利用FLUENT 6.0软件可以较好地模拟空泡绕流现象,能够正确反映空泡外形随空化数变化的规律,并且能够较准确地捕捉到空泡尾端回射流现象.

| Abstract: | Cavitation flow fields around axisymmetric revolution bodies were simulated by the aid of FLUENT 6.0 CFD software.Volume fraction was introduced to distinguish water and vapor phases.Simulation results keep good accordance with other researchers' simulation and experimental results.It is shown that the natural cavitation phenomena can be well simulated by FLUENT,the trend of cavity shapes changing with cavitation number is properly reflected and the reentrant jet is also captured. |
