| 摘 要： | 提出了将带微小控制角的有限体积法(FVM ISCA)应用于锅炉火焰针孔成像的计算方法。其步骤如下：首先选用一合适的常规有限体积法计算出炉膛内的辐射强度场,然后根据几何光学确定出进入针孔投射到CCD相机靶面每一个像元上的辐射方向,最后由FVM ISCA逐一计算出这些辐射强度来。

| Abstract: | The finite volume method with infinite small control angles (FVM+ISCA) was applied to compute pinhole image formation of radiative energy of furnace fire. Firstly, a suitable finite volume scheme was selected to calculate the radiation intensity field in the furnace. Then, according to the geometric optics the direction of the intensity was determined which is incident on every pixel of the target of the CCD camera through the pinhole. Finally, these intensities were calculated one by one by using the FVM+ISCA. |
