| 摘 要： | 为了便于在红外成像仿真中对目标表面温度场进行计算,提出了一种基于可达辐射能的目标表面辐射传递系数计算方法。分别用公式法、蒙特卡洛法和可达辐射能计算法计算了两两垂直表面和两两平行表面模型间的辐射传递系数,并进行了仿真验证。结果表明,该可达辐射能计算方法在确保计算精度满足要求的同时,在计算效率上相对于公式法和蒙特卡洛法都有较大提高。

| Abstract: | To calculate the temperature field on target surface conveniently during infrared imaging simulation, a method for calculating the radiation transfer coefficient on target surface based on accessible radiant energy is proposed. The formula method, Monte Carlo method, and accessible radiant energy calculation method are respectively used to calculate the radiation transfer coefficient between two vertical surfaces and that between two parallel surface models. The calculations are verified by simulation. The result shows that the calculation efficiency of the accessible radiant energy calculation method is improved greatly compared with the formula method and the Monte Carlo method, while its calculation accuracy is ensured to meet the requirements. |
