【摘要】 本文在修改原始KTSS燃烧模型的基础上,研究了热波理论模型的数值特性,并在较宽|dp/dt|范围内进行数值分析计算,发现在大|dp/dt|(原KTSS模型中β≥10)值下,燃速值并未发散溢出,最后又回到了稳态值。燃速“溢出”只是一个数值困难,而不是热波燃烧模型的解。同时,还对数值结果同实测结果进行了比较分析。更多还原

【Abstract】 Based on a modified KTSS model, the numerical characteristics of the thermal-wave combustion models are investigated and numerical calculations are carried out for a wider range of. The numerical solutions show that with higher values of (in the original KTSS model, when β>10.0) unsteady burning rate "runaway" does not appear and will return to the steady value thereafter. Burning rate "runaway" is only a numerical difficulty but is not a solution to the thermal-wave combustion models. Meanwhile the predicted unsteady burning rates are compared with experimental results.更多还原
