Numerical Analysis of Diffusion of Leaked UDMH on a Cliff

Abstract:

Built-in VOF model and k-ε turbulence model in Fluent were used to simulate the evaporation and diffusion of the pool formed by leaked UDMH on a cliff. Different situations in three wind speeds were calculated, and the diffusion mode and concentration distribution law were analyzed. The results show that there is a large poisoned area formed on the cliff, and people under the cliff should escape to upwind immediately and the emergency personnel should access the accident spot along the back of the cliff.
