| Abstract: | A method for intermittently flushing the surface of an electromagnetic sensor with high pressure gas is proposed. We designed high pressure gas nozzles and established a gas-liquid two-phase flow dynamics model. The numerical simulation analysis of the underwater jet process was carried out using Fluent simulation software. Simulation results show that high pressure gas can cover entire sensor suface. In addition, we designed a high-pressure gas automatic flushing device and used it for marine testing. The results show that the device has better effect on biological fouling control of the underwater electromagnetic sensor |
