从壁面热蚀痕迹的形成机理出发,根据影响热蚀痕迹形成的因素,借助数学方法建立了以壁面热负荷的累积效应来表征痕迹深浅程度的半物理预测模型,并嵌入FDS源程序,成功将半物理预测模型与FDS源程序耦合,实现了壁面热蚀痕迹的数值重构,弥补了现有软件的不足,进一步完善了数值重构技术.
The probability of researching the thermal ablation patternon by numerical reconstruction
Starting from the formation mechanism of the wall thermal erosion traces, and according to the factors influencing the thermal erosion trace formation, a semi-physical prediction model of characterizing the degree of difficulty of the traces by the cumulative effects of wall heat load was established. The model was embedded in FDS source code, which reconstructed the thermal ablation pattern. The study compensated for the deficiencies of the existing software, and improved the numerical reconstruction technique.
