Study on the Diffusion Mechanisms of Methanol Leakage in Confined Spaces [PDF]

Sustainability
With the rapid expansion of methanol-powered shipping, the emphasis within the industry has increasingly been placed on ensuring the operational safety of these alternative fuel vessels. In this study, the mixture and realizable k-ε models are adopted to simulate the liquid methanol leakage model, and the predictive accuracy of the model is verified ...

Heat-content and diffusive leakage from material sets in the low-diffusivity limit ^* [PDF]

Nonlinearity, 2021
Abstract We generalize leading-order asymptotics of a form of the heat content of a submanifold (van den Berg & Gilkey 2015) to the setting of time-dependent diffusion processes in the limit of vanishing diffusivity. Such diffusion processes arise naturally when advection–diffusion processes are viewed in Lagrangian coordinates.

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 ...

Progress of research on diffusion rules of spilled oil from onshore oil pipeline and leakage consequences

You-qi chuyun, 2020
Oil pipeline leakage will cause direct economic losses and even adversely affect the surrounding environment and residents along the pipeline. It is crucial to be aware of the seepage, surface diffusion and evaporation of leaked oil in the surrounding ...
