| Abstract: | A method of describing the maximum fuel/air deflagration pressure in a closed vessel was presented by using the half-empirical method. The method used the available energy concept to predict the maximum gas deflagration pressure in a closed vessel, and the predictive values and thes testing values of the maximum pressure of eight fuel/air systems were given. The deviation between the predictive values and the testing values was from-0.138 to 0.103MPa,and the deviation between the maximum pressure value predicted with the ideal gas law method and the testing values was from-0.138 to 0.827MPa. |
