| 摘 要： | 通过推板造波方法,应用FLUENT动网格技术(Dynamic Mesh)及UDF(User-defined function)建立数值波浪,从而构建数值水槽。对建立的数值波浪与气泡运动方程耦合求解,分析气泡在波浪中的变形与运动。结果表明,波浪中气泡相对静水中更容易保持稳定的球形,且不易发生聚合。这将为舰船尾流中气泡运动研究提供有价值的参考。 |

| Abstract: | In this paper,a numerical wave model was established based on the technology of Dynamic Mesh and User-defined function in FLUENT,and the wave was produced by the motion of wave-making plate.To investigate the bubble deformation and movement,coupling calculation of wave model and bubble motion equation was carried out.The results show that the bubble more easily maintained spherical shape and no coalescent.This research provides worthy references for the investigation of warship wake. |
| Keywords: | piston wave making bubble motion numerical simulation |
