Abstract

Abstract: Through constructing a large- size experiment platform for gas explosion, the distribution and diffusion of gas leakage within the residential buildings were stimulated. By collecting data by the mobile and fixed sensors, the changes of gas leakage concentration in different positions over time were collected and the laws of gas leakage diffusion in buildings were summarized. Meanwhile, by building a concentration map, the changes of gas concentration in the kitchen at different moments after gas leakage were presented.

Key words: gas leakage, concentration distribution, diffusion laws, concentration map
