In a 5.125 liter cylindrical container, explosion experiments of two kinds of bituminous coal are carried out under different initialized temperature and pressure, different mean particle sizes and various coal particles concentrations. A dedicated pressure sensor and a high rate data acquisition system are incorporated. The sequence control based on the accurate electronic device is carefully implemented. The pressure histories are recorded. Through further data processing, the pressure rising rate and etc. are incorporated in the analysis. All the work and results will provide important reference for industry. Jiahu Li (Engineering Thermal Physics) Directed by prof. Weiping Yan...
