摘　　要：为了探讨辐射热防护测试(RPP)仪在试样表面产生的辐射热通量分布,采用蒙特卡罗法对RPP建立了数值模型,并进行了实验验证.计算结果与实验结果十分吻合,证明了模型的合理性与正确性.计算结果显示,在试样的入射表面,辐射热通量呈椭圆形分布,能量集中在内部区域,在中心区域的辐射热通量分布相对均匀,两侧边缘的辐射热通量相对较低.研究结果为进一步研究RPP测试试样的防护效果提供了理论依据.In order to analyze the radiant heat flux distribution at the incident surface of test specimen in radiant protective performance（RPP）apparatus,a numerical model based on the Monte Carlo method was developed.And experiments were conducted to validate the model.It is found that the predictions of the model show a good agreement with the experimental results.Further,at the incident surface of the sample,the calculation results show an oval-shaped distributed heat flux area with a high energy concentrated in the interior region.The radiant heat flux distribution is relatively uniform at the central region,and relatively low on both sides of the edge.The results will provide a theoretical guideline for further research on the protective effect of the specimen in RPP testing.
