摘要: |
为研究水下制氢反应室的动态过程规律,基于化学反应动力学和单液滴运动学得到合金/水反应转化率,并在最小自由能法计算得到生成物各组分摩尔数的基础上利用质量守恒方程得到室内各物质质量变化规律。在建立非线性移动边界螺旋管动态模型的前提下,利用能量守恒方程得到室内热力参数变化规律,进而完成制氢反应室动态过程详尽模型的建立。利用该模型编写计算程序,完成某水下制氢反应室动态过程仿真。结果表明,各仿真曲线较好地反映了对应参数的动态变化规律,验证了模型建立与仿真的正确性;合金/水反应转化率决定了反应室的物质质量变化规律及其能量释放特性。该模型可以作为制氢反应室动态特性分析及其过程控制研究的基础模型。 |

Abstract: |
To study the dynamic characteristics of hydrogen generation reactor, the reaction conversion rate of alloy and water was calculated by chemical reaction dynamic and kinematic analysis of reaction drip, and the mass variation of each substance in reactor was described by the law of mass conservation based on whose molar value was got by the minimum Gibbs free energy method. Based on the law of conservation of energy and a nonlinear moving-boundary model of helical tube, the dynamic process model of this reactor was established. The dynamic process simulation of an underwater hydrogen generation reactor was realized by using the calculation program based on the dynamic model. Results show that the simulation curves can reflect the variation law of parameters during the dynamic process, which proves the validation of the modeling and simulation. The reaction conversion rate determines the variation law of mass and the characteristics of releasing energy in reactor. The established model can be used as the basic foundation for performance analysis and control study of underwater hydrogen generation reactor. |
