| 摘 要： | 为了研究辐射能量在火药床内的分布情况,该文采用了Monte-Carlo方法, 模拟颗粒床中辐射换热的实际物理过程,通过对能束的追踪,得到辐射热流量分布的统计规律,火药床对电弧辐射有屏蔽仿真,辐射能量只能作用在电弧周围很小的距离内.该方法能够为电热化学炮点火机理的研究提供一定的理论依据.

| Abstract: | For the investigation of the radiative energy distribution in the propellant bed, a Monte-Carlo technique was used to simulate the energy bundle travelling through the voids of the bed, and the statistical regularity of the distribution of radiative heat flow rate was obtained. The propellant bed has the screening effect on arc plasma radiation, and has the effect of radiative energy ranges over a small field of the arc surrounding. This method can be used for the investigation of the ignition processes in the electrothermal-chemical guns. |
