A numerical analysis on radiation configuration factors of surface-model pigs to rectangular planes on gable roofs

采用三站面模型猪、计算机图形学和数值积分法，对猪对屋顶矩形平面的热辐射构型因子进行了数值计算。活重分别为27kg、65 kg和88kg的表面模型为三维图形猪，具有许多表面安装的三角形斑块。以猪体重量、猪体与猪体之间的距离、猪体顶板的倾斜角为参数，给出了确定各因素的平面尺寸函数图。

Thermal radiation configuration factors of a pig to a rectangular plane on a roof were numerically calculated by using three standing surface-model pigs, computer graphics and numerical integration methods. The surface-models with live weights of 27, 65 and 88kg were three-dimensional graphic pigs with many surface-mounted triangular patches. The figures for determining the factors were presented as a function of the dimensions of the plane with the pig body weight, the distance between the plane and the pig, and the inclined angle of the roof as parameters.
