碳烟颗粒气氧煤油发动机尾焰红外辐射有限体积法 Carbon Gas oxygen/kerosene engine Plume Infrared radiation Finite volume method

摘要

提出了一种考虑碳烟颗粒的气氧煤油发动机尾焰红外辐射特性计算方法, 首先对气氧煤油发动机纯气相内流场进行计算, 然后以喷管喉部作为气体和固体碳烟颗粒的入口边界计算发动机尾焰流场, 最后以发动机流场参数分布为基础, 采用有限体积法和伪气体理论对发动机尾焰红外辐射特性进行计算。进行了气氧煤油发动机点火实验, 并将计算结果与实验结果进行对比分析。结果表明, 燃烧室内两个压力测量点的测量与计算误差分别为1.4%和3.4%, 燃烧室内计算温度与热力学计算误差为2.16%, 证明了燃烧室流场计算模型的准确性。含有碳烟颗粒的尾焰流场计算结果与热像仪测量结果比较吻合, 证明了尾焰流场计算方法和模型的准确性。 4.3 μm波段尾焰红外成像计算结果与工作在4.3 μm波段的红外热像仪测量结果吻合比较一致, 证明了尾焰红外辐射特性计算方法和模型的准确性。

Abstract

A method for calculating infrared radiation characteristics of the gas oxygen/kerosene (GOX/KERO) engine plume considering soot particles was proposed, first of all, the simulation of engine internal flow field was carried out, and the plume flow field was calculated using the nozzle throat as the inlet boundary of the gas and carbon particles, infrared radiation characteristics of the engine plume were calculated with the finite volume method (FVM) and the pseudo-gas theory based on the field parameters. The ignition experiment of the gas oxygen/kerosene engine was carried out, and the calculated results were compared with the experiment results. It was found that, the pressure errors between measurement and calculation of two pressure measurement points in the chamber were 1.4% and 3.4%, the temperature error between thermodynamics and calculation in chamber 2.16%, which verified the accuracy of the chamber flow field calculation model. The calculation results of the plume flow field containing the soot particles were in good agreement with that of the thermal imager, and the accuracy of method and model of plume flow field calculationwas proved. The plume infrared imaging in the 4.3 μm band of the calculation was in good agreement with that of the thermal imager, and the accuracy of method and model of plume infrared radiation calculation.
