摘要
建立了适合于多种燃料燃烧过程的零维数学模型，并利用优化算法 Ｐｏｗｅｌｌ法对 Ｖ２ｂ 函数中的各参数进行优化求解。应用此模型对实机燃用纯甲醇的压燃过程进行 了放热率的变工况拟合和循环变动率的数学统计分析。分析的参数包括零维燃烧模型 中各特性参数、平均指示压力、最高燃烧压力、着火延迟期及放热率与着火延迟期的 相关系数等。
A zero-dimension combustion model which is suitable for the multi-fuel combustion process has been developed. The V2b function is calculated by the Powell Optimized Algorithm. The model is used for the analyses of methanol combustion processo They have two fields as follows, a) the heat release rate curve fitting on several testing conditions, b) the statistical analyses of variation of the cycle to cycle. The characteristics concerned in the model analyzing include all of the variables in zero-dimension model, mean indication pressure, maximum combustion pressure, ignition delay and the correlation coefficient between heat release rate and ignition delay, etco
