| | The dynamic behavior of the trimolecular autocatalytic reaction A+2X 3X in one and two dimensions is studied by numerical simulations.It is found that the asymptotic behvior of the reaction can be, depending on the microscopic reaction rules, quite different from or the same as the equilibrium limit predicted by classical chemical kinetics(mean-fieldtheory)in both one and two dimensions. | | 通过数值模拟对3分子自催化反应A+2X3X在一维和二维介质中的动力学行为进行了研究。发现在一维和二维情形下,如果施以不同的微观反应规则,该反应的渐近行为既可能偏离经典化学反应动力学(平均场理论)所预言的平衡极限行为,也可能与之一致。 | | 文摘来源 | | The conditional moment closure (CMC) formulation considering both molecular and turbulent diffusions is derived and applied to simulate two dimensional nonpremixed turbulent reacting flows. Calculated results show good agreement with experimental ones. Results show that finite Damkohler number makes conditional averaged variables depart from their equilibrium values and the deviation is the maximum near stoichiometric mass fraction. The increasing Damkohler number increases conditional and unconditio... | | 推导了考虑分子和湍流扩散的条件矩封闭方程,并利用其模拟了二维非预混湍流反应流,计算结果与实验结果符合良好.结果表明,有限值的Damkohler数使条件平均变量偏离其平衡状态,且在混合分数η位于化学恰当比下的混合分数附近时偏离最大.Damkohler数的升高还使得条件和无条件平均的反应速率升高,并使条件平均变量向其平衡状态值趋近.本文还观察到以往的简化维数处理会引起一定的偏差.因此,对于一般的椭圆型反应流动,建议采用考虑扩散效应的CMC控制方程 | | 文摘来源 | | Through introducing a supercritical fluid into the conventional methanol synthesis process,a supercritical phase methanol synthetic technology has been developed. This new process can better solve the problems of reaction heat removing from catalyst bed and thermodynamic equilibrium limit. As the reaction and separation are realized at the same time, the one through conversion of CO can be over 90%. The experimental research results are reported in this paper. | | 超临界相合成甲醇新工艺通过在反应过程中引入超临界流体 ,从根本上解决了传统合成甲醇工业中的床层传热问题与热力学平衡限制问题 ,实现了反应分离一体化 ,并使合成气单程转化率达到 90 %以上 | | 文摘来源 | |   | | << 更多相关文摘 |
