摘要
提出通过随机方向法由计算机赋初值求燃烧产物平衡组成的改进吉布斯自由能法。讨论了影响随机方向法求解初值个数和区间选取的因素。用改进法和原吉布斯自由能法计算了肼和氧的燃烧产物。结果表明,二者结果相同。改进算法具有算法简单、计算收敛、符合约束条件的初值完全由计算机生成的优点。
A Gibbs free energy method improved via initiating initial values by computer with random direction method was presented to calculate the equilibrium composition of combustion products.The factors of solving initial number and interval selection affecting the random direction method were discussed.Combustion products of hydrazine and oxygen obtained by improved and original Gibbs free energy methods are same.The advances of improved arithmetic are simple,convergent and initial value matched a constraint condition completely which is generated by computer.
