In order to solve the problem that the setting parameters such as water jet pressure, angle and target distance were lack of basis due to the difficulty in directly observing the process of water jet cleaning in-situ leaching uranium production wells in submerged environment. Fluent numerical simulation software was used to compare the status of air jet and water jet, and the influence of water depth, outlet pressure, target distance and impact angle on submerged jet was discussed. The results show that the flood environment has a great effect ...
