The article presents and analyzes experimental studies of the distribution of ink in the water and the explosive combustion of methane-air mixture. The authors described the processes of explosive mixtures’ formation in a room in case of methane leakage. The article also presents the visualization of the formation process of explosive mixtures. The mathematical model and calculation model adequately describe the process and confirm the results of the experiments. The coefficient of turbulent diffusion under the given conditions is indirectly determined. Explosive mixtures usually form accidental leaks of combustible substances from household stoves in the residential sector. The consequences of such accidents are human losses and material damage. As the analyses have shown the formation of gas-air mixtures of combustible substances is affected by: turbulent diffusion coefficient, the parameters of the sources of accidental releases, the physical properties of gas-air mixtures and other. Explosive substances are not visible to the human eye. In order to visualize the physical process we will use the model distribution and dissolution of ink in water. Based on the analysis of the works of different scientists it was concluded that the laws of distribution of liquids and gases are similar. The experiments were carried out in order to study the distribution of ink in the water and explosive combustion of methane-air mixture to determine and describe the process of formation of explosive mixtures in a room in case of methane leakage. The coefficient of turbulent diffusion is a key parameter that can accurately predict the development of these emergency situations.
