| 摘 要： | 为研究双模态燃烧室的模态转换规律,采用计算流体动力学(CFD)方法,对氢燃料模型燃烧室在不同当量油气比、飞行马赫数、燃料喷射方式下的流场进行了数值模拟,并与试验结果进行对比,两者相互吻合.研究结果表明:当量油气比提高、飞行马赫数降低及双面喷射燃料均使燃烧室更趋于亚燃工作模态.

| Abstract: | To investigate the mode transition in the dual mode combustor,using the method of computational fluid dynamics(CFD),numerical simulation of hydrogen-fueled combustor flow field was conducted at different equivalence ratios,flying Mach numbers and fuel injection modes.The simulation results are found to agree well with the experimental data.Results show that increase of equivalence ratio and reduction of flying Mach number along with two-sides injection make the combustor tend to work in sub-combustion mode. |
