A diffusion approach to the electrolyte leakage 
from plant tissues

Physiologia Plantarum, 2005
The exchange of ions between plant tissues and the external solution in vitro exhibits prominent biphasic kinetics. This is generally ascribed to the different contribution of the two compartments – apoplast and symplast – involved in the process. In this regard, an electro‐diffusion model of the leakage is proposed in the paper.

DroidTrack: Tracking Information Diffusion and Preventing Information Leakage on Android

2013
An app in Android can collaborate with other apps and control personal information by using the Intent or user’s allowing of permission. However, users cannot detect when they communicate. Therefore, users might not be aware information leakage if app is malware.

Numerical Simulation of Gas Leakage and Diffusion Based on FLUENT

Advanced Materials Research, 2013
A two-dimensional unsteady flow model was established by Realizable k-ε turbulence model and SIMPLE algorithm, which was applied to conduct numerical simulation of sudden leakage and diffusion of coal gas in the plant area. Then, time-dependent distribution laws of coal gas under different influencing factors were analyzed.

Numerical Simulation of Leakage and Diffusion of Liquid Ammonia Tank

2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and Control, 2014
The model for the leakage and diffusion of liquid ammonia tank established using the species transport and reaction module of Fluent in order to investigate the leakage of liquid ammonia due to storage tank failure. The corresponding influencing laws were obtained by changing the height of leakage source and the size of leakage aperture in the ...

Near-field vertical diffusion of liquid ammonia leakage

Physics of Fluids
With societal and economic development, ammonia has become an important product in the chemical industry, gaining increased importance among energy sources as a carrier for hydrogen storage and transportation. As liquid ammonia transportation through pipelines generally occurs at medium to low pressures, the leakage process involves complex jet ...

Fluid leakage effect on analysis of a vaned diffuser of SHF

2014
The paper presents the results of numerical analysis on the local and global internal flow behaviour at the inlet of the vaned diffuser of a radial flow pump model, taking into account the effect of fluid leakages for various flow rates and a given rotation of speed.
