| 摘 要： | 针对液体火箭发动机羽烟紫外辐射的空间分布问题,建立三维数值计算模型.该模型采用标准κ-ε湍流模型和PDF模型仿真羽烟流场的状态参数,根据HITRAN数据库计算流场内吸收系数分布,并利用离散坐标法求解辐射传输方程,计算三维空间的紫外辐射分布.测试结果表明:三维紫外辐射模型的计算结果与实验数据一致,能够反应不同视角下液体火箭发动机羽烟紫外辐射强度的空间变化.

| Abstract: | To analyze the spacial distribution of UV radiation from liquid rocket engine plume,a 3-D numerical model has been built.The standard κ-ε model and probability density function(PDF) model were adopted to compute the flow-field properties of the plume.Combined with HITRAN database,the distribution of absorption coefficient was calculated,and the radiation transfer equation could be solved by the discrete ordinate method.Test results show that the 3-D computation model can provide numerical data that agree well with measured experimental data.It also could reflect the spacial distribution of UV radiation from the hydrogen-oxygen rocket engine plume at different angles of view. |
