Simulation of Diffusion Trend of Unexpected Gas Leak Accident based on Google Earth

This paper presented a set of methods for dynamic prediction and simulation of the diffusion trend of leaked gas based on Google Earth technology and Gaussian diffusion model targeted at the sudden hazardous chemicals leak accident, providing a set of design solution, and performing the experimental verification for the model and design by taking the example of carbon monoxide, from which the results showed that with the method it quickly and intuitively predicts the gas diffusion trend, provides strong support for the emergency relief and rescue work in case of such sudden gas leak accident.
