It is difficult to separate the effects on stability of the propellant properties from those of the injection scheme . 要把推进剂性质对稳定性的影响与喷射型式的影响分开是困难的。
It has now been demonstrated that fluid injection schemes can produce a sufficient side force to meet the requirements of many applications . 现在已经证明,流体喷射的方案能产生足以满足很多用途所要求的侧向力。
Experiments on the lean blowout limit of cavity flame holder with liquid kerosene fuel on room temperature were conducted with various cavities and injection schemes 对基于常温液体煤油燃料的凹腔火焰稳定器的贫油稳焰范围进行了试验研究,比较了不同凹腔结构尺寸和不同喷注方式。
The combustion and flow process of cavity flame holder with liquid kerosene fuel on room temperature were investigated experimentally , with different fuel equivalence ratio and injection schemes 在燃烧状态下,对基于常温液体煤油燃料的凹腔火焰稳定器的燃烧与流动特征进行了试验研究,并比较了不同当量比和不同燃料喷注方式。
In order to make the factor be taken into full consideration and to prevent from being loss when designing production and gas injection schemes , it is necessary to study the method for prediction of asphtene precipitation as to minimize or avoid the harm by the precipitation 因此,有必要研究沥青沉积的理论预测方法,帮助人们在设计注气与生产方案时,充分考虑这一因素的影响,以避免或减小它的危害。
The result of investigation on drags of cavities under combustion condition , with different injection schemes and fuel equivalence ratio , indicates that it is smaller than it ’ s of cold flow , and decreases with increasing fuel equivalence ratio , and could be converted into the 研究发现:凹腔火焰稳定器热试阻力小于冷流阻力,并随着当量比的增加而减小,最终会表现为正推力。综合论文研究成果,提出了多凹腔燃烧室设计技术。
