本文对采用单激光点火系统和双激光点火系统的氢燃料周转式发动机的燃烧和点火过程进行了数值研究。建立了考虑湍流与化学反应相互作用的过程模拟计算方法。采用详细的氢气燃烧化学动力学模型。结果表明，由于转子相对于发动机壳体的复杂运动，燃用H2的旋转式发动机的着火和燃烧过程是一个高度瞬变的过程，燃烧室内的燃烧前沿发生了特殊的变形和伸展。对单激光点火系统和双激光点火系统进行了模拟，比较了点火效率和氢燃尽速率。对燃用天然气的旋转式发动机的燃烧室压力进行了评估，并与实验数据进行了比较。结果表明，采用双激光点火系统的氢燃料旋转式发动机由于效率高、碳基排放接近零，在替代汽车工业中具有潜在的应用前景。
In this paper the combustion and ignition process in the hydrogen-fueled peripheral-ported rotary engine with single and dual laser ignition systems was studied numerically. The computational method was established for the process simulation including interaction between turbulence and chemical reactions. The detailed chemical kinetic model of hydrogen combustion was used. It was shown that the ignition and combustion process in the H2-fueled rotary engine is highly transient with specific distortion and stretching of the combustion front in the combustion chamber due to complex motion of the rotor relative to the engine housing. The single and dual laser ignition systems were simulated to compare the ignition efficiency and the rate of hydrogen burning out. The evaluation of pressure in the combustion chamber was performed and compared with the experimental data obtained for the rotary engine fueled by natural gas. It was shown that the H2-fueled rotary engine with the dual laser ignition system has potential application in alternative automotive industry due to high efficiency and near-zero carbon-based emission.
