基于空化喷射技术的水下机器人射流清洗仿真与 实验


目 的

污染物质的存在会引起海底环境中的许多经济和 生态问题. 本文以遥控无人潜水器 (ROV) 为基 础承载平台, 实现基于空化喷射清洗技术的水下 结构表面附着物清洗.


将空化射流清洗技术与 ROV 结合, 并利用空化 泡在清洗表面区域溃灭产生的微射流冲击, 以达 到清理水下表面附着物和污垢层的目的.

方 法

1. 通过计算流体动力学 (CFD) 仿真与实验, 针 对 ROV 水下喷射模型, 在不同状态和不同参数 下对水下射流的规律进行测试与比较. 2. 实验对 比验证在不同喷射距离下所设计的空化射流清

结 论

1. 当入口压力 P=30 MPa, 孔径 d=2 mm, 出口长 度 L=16 mm 和出口直径 D=16 mm 时, 水下喷嘴 具有更高的清洁度和清洁效率, 可以满足清洁要 求. 2. ROV 喷嘴离水下泥浆越远, 冲刷深度越浅. 3. 所设计的 ROV 空化喷射清洁装置与目标的距 离越近, 清洗强度越高; 然而, 当压力恒定且距 离太近时, 过度阻力会削弱冲洗强度. 洗装置清理海底生物的能力.
