Hemispherical finite element model of combustible gas was created by Fluent software to simulate the gas cloud explosion. The temperature field of unconfined gas cloud explosion was studied by data fitting. The result shows that, each monitoring point experienced four stages: rose to peak temperature; dropped to a high temperature quickly; maintained in this high temperature and lasted some time; declined slowly. Double fold line model can fit the curves of temperature change, and get the temperature-time functions finally.
