摘　　要：高性能黑体辐射源是高精度复现辐射温度的关键装置。采用有限体积法模拟计算了黑体空腔积分发射率,其结果与Monte-Carlo法计算结果吻合良好,且在高发射率时较Monte-Carlo法能更准确地模拟空腔积分发射率的变化趋势。基于响应面试验设计,模拟了圆锥-圆柱黑体空腔长径比L/D、光阑开孔直径比Da/D、圆锥顶角θ和腔壁材料发射率ε及其交互作用对空腔积分发射率εe的影响。结果表明:Da/D和ε对εe影响显著;L/D和θ对εe的影响不显著。研究结果可为高性能黑体辐射源的研制和研究提供借鉴。High-performance blackbody radiation source is the key equipment for highly precision reproduction of radiation temperature.Integrated emissivity of blackbody cavity numerically simulated by finite volume method (FVM) has a good agreement with the result computed by Monte-Carlo method (MCM).Moreover,the FVM can predict the trend of integrated emissivity more accurately than MCM.Based on design of experiment with response surface method,key factors and their interactions of a cylindro-conical cavity,such as length-to-diameter ratio L/D,aperture diameter to cylinder diameter ratio D a/ D,cone angle θ,and intrinsic emissivity of the cavity surface ε,are analyzed for integrated emissivity ε e.The results show that D a/ D and ε are significant factors;L/D and θ have less influence on ε e.The results can provide references for the manufacture and study on high-performance blackbody radiation source.
