- 摘要:
- 为火箭发动机喷管设计及其冷却系统的设计提供有效参考数据作为应用背景，计算喷管壁所受的红外辐射热流。分别推导了有限体积法和反向蒙特卡罗法适用于不含粒子条件下喷管壁面所受红外辐射热流的计算公式，并针对不同的边界条件设定，重点分析了有限体积法的特性，并提出了有限体积法的局限性。最后，以某三维双圆弧喷管模型为例，用有限体积法和反向蒙特卡罗法自主编写程序计算在不同边界设定下壁面受到的红外辐射热流密度。通过计算结果对有限体积法的局限性进行了论证，同时肯定了反向蒙特卡罗法在壁面辐射热流计算上的优势。
- Abstract:
- The radiative heat flux on the wall of nozzle is calculated to provide the effective reference data for design of rocket engine nozzle and its cooling system. The formulas of finite volume method (FVM) and (backward Monte Carlo method) BMCM, which are appropriate for calculating the radiation heat flux density of nozzle's wall, are derived without the influence of particle. According to different boundary conditions, the characteristics of FVM are analyzed, and the limitation of FVM is proposed. At the end of the paper, taking a 3D model of double-arc nozzle as an example, the self-complied programs in FVM and BMCM are utilized to calculate infrared radiation heat flux density on the nozzle wall according to the different boundary setting. According to the results, the limitation of FVM is verified, and the advantage of BMCM in calculating the radiative heat flux on the nozzle wall surface is affirmed.
