Leakage diffusion of underwater crude oil in wind fields [PDF]
SpringerPlus, 2016 Leakage of underwater crude oil pipes causes severe pollution to soil and water, and results in great economic loss. To predict the diffusion area of spilled oil before it reaches the water's surface and to reduce the time required for emergency response, numerical simulations were conducted on underwater spilled oil diffusion of bare crude oil pipes ...

Experiment of N2O4 Leakage and Diffusion in A Closed Space
Academic Journal of Science and Technology, 2023 The paper, by experiment of physical simulation, researched the leakage and diffusion law of N2O4 in a specific closed space. To simulate N2O4 leakage, the experiment pumped a certain amount of N2O4 gas into a specific space from a simulated leak point. And some electrochemical sensors were used to detect the concentration of N2O4 gas in some places in
