Flow and radiation of plume from solid rockets with scaling ratio from 0.1 to 1 have been computed. The radiative transfer equation (RTE) is solved by the finite volume method (FVM) in infrared band 2~6  μ.m。羽流气体的光谱特性已经用加权 - 灰气（WSGG）模型和Al₂O._3.MIE散射模型已经解决了颗粒。我们的研究表明，随着火箭发动机的缩放比率的降低，羽流的辐射强度随着缩放比的1.5〜2.5功率而降低。羽流气体的红外辐射显示出强烈的光谱依赖性，而Al₂O._3.粒子显示灰色财产。在羽流气体的峰值吸收光谱中，固体火箭羽流的高温芯的光谱辐射强度增加。AL.₂O._3.颗粒是火箭羽流中的主要辐射成分，其散射系数远大于其吸收系数。来自不同缩放固体火箭的褶皱之间的频谱变化之间存在良好的相似性。方向羽流辐射随着方位角的增加而上升。SN - 1110-757X UR - HTTPS：//Doi.org/10.1155/2015/627351 Do - 10.1155 / 2015/627351 JF - 应用数学PB - Hindwi Publishing Corporation KW - ER -
