pulse-operater chamber

The model considered the influences of the mode of reactants supply, the chemical reaction in the combustion chamber, radiation and convection heat loss of the combustion chamber wall, as well as fluid density changes in the tailpipe on stable operation of pulse combustion.

该模型考虑了反应物的供给方式、燃烧室内的化学反应、燃烧室壁面辐射与对流传热损失以及尾管内流体的密度变化对脉动燃烧稳定运行的影响。

The minimum time of pulse combustion is determined by the FLUENT simulation of the thermal processes in the furnace chamber of XR-II.

利用FLUENT软件，通过对XR-II炉内热工过程进行模拟，确定了最短脉冲燃烧时间。

Because fuel distribution in detonation chamber governs the performance of pulse detonation engine ( PDE), some controlled fueling experiments were designed to test the effect of partial tube fills on PDE performance.

因为爆震室中燃料的分布和填充程度决定了脉冲爆震发动机（PDE）的性能，故试验中精心控制燃料填充程度，以研究爆震管中填充程度对脉冲爆震发动机性能的影响。
