论文摘要
提出和讨论了一种计算具有详细和降低化学的气态燃料混合物的最低点火能，并通过时间依赖性保护方程的数值整合在球面对称配置中，并进行了讨论，并测试其一般特征和准确性。该方法应用于由38步Arrhenius化学描述描述的甲醇 - 空气混合物，并通过基于反应中介机构的稳态近似值的8步化学描述。预测与可用实验测量结果的比较产生了合理的协议，并支持了计算方法的鲁棒性以及8步减少在实现准确预测中的实用性。
A method for computing minimum ignition energies for gaseous fuel mixtures with detailed and reduced chemistry, by numerical integration of time-dependent conservation equations in a spherically symmetrical configuration, is presented and discussed, testing its general characteristics and accuracy. The method is applied to methanol-air mixtures described by a 38-step Arrhenius chemistry description and by an 8-step chemistry description based on steady-state approximations for reaction intermediaries. Comparisons of predictions with results of available experimental measurements produced reasonable agreements and supported both the robustness of the computational method and the usefulness of the 8-step reduction in achieving accurate predictions.
