Based on the fact of the toxic gas diffusion from gas explosion, Gaussian puff model was improved, and the formula in accord with the diffusion rule of toxic gas from gas explosion in mines was set up.

Analysis of parameters for numerical simulation of poison gas leakage and diffusion in destructive earthquake;

In this paper, the numerical simulation and dynamic emulation of poison gas leakage and diffusion that possibly occur in the destructive earthquake are studied.

In this paper, the simulation of poison gas leakage and diffusion based on GIS(ArcView3.

In this paper,we study a gas dispersion model under dynamic wind conditions,based on the Gaussian dispersion models such as Gaussian plume model and puff model that are widely used in previous literatures.

Positive analysis of floating population and illegal drug diffuseness in Yunnan;

In this article the studies on moisture diffusion process, hygroscopic stresses and moisture-induced vapor pressure are reviewed, with the emphasis on the theoretical analysis, parameter characterization and its experimental measurement and validation, as well as the finite element simulation.

This paper analyzes rules of moisture diffusion in PBGA and PQFP packages and influence of temperature during dry baking using finite element analysis models.
