| Abstract: | Computative program DUTGB1 has been worked out for the hydrocarbon gases burning and explosion under the condition of heat insulation (S = const) and spherical surface lamellar burning in a closed vessel. The burning temperature and explosive pressure of thirteen kinds of hydrocarbon gases was computed under various original conditions. Having checked the numerical solution against the values of the paper experiments and literatures, the error of burning temperature is in 11. 4-17. 6%, the error of explosive pressure in -9. 09%-10. 16%, and the error of explosive pressure of an alkene or an alkane in -5. 51%-8. 84%. |
