Gas Diffusion Model and Its Application based on CFD Theory
Abstract
In order to reduce the loss and impact of the unexpected leakage of hazardous chemicals, the paper makes use of the computational fluid mechanics theory and applies the commercial software, FLOVENT, to imitate the steady state and transient state of six scenes of the diffusion scope and concentration change of NH3 and H2 in different wind directions and leak location; furthermore, it takes the simulated result as the basis to analyze the diffusion length and impact scope of the characteristic concentration, both of which will be the evidence for occupants evacuation.
