辐射角系数是计算人体与辐射板间辐射换热量的一个重要参数,针对人体与辐射板之间辐射角系数问题求解的复杂性,使用长方体模型代替站立姿态时的人体形状,进行辐射角系数的计算。以辐射顶板为例,运用周线积分法和代数法建立了任意位置下人体与辐射板之间辐射角系数的数学表达式,并对结论的合理性进行了验证。
輻射角繫數是計算人體與輻射闆間輻射換熱量的一箇重要參數,針對人體與輻射闆之間輻射角繫數問題求解的複雜性,使用長方體模型代替站立姿態時的人體形狀,進行輻射角繫數的計算。以輻射頂闆為例,運用週線積分法和代數法建立瞭任意位置下人體與輻射闆之間輻射角繫數的數學錶達式,併對結論的閤理性進行瞭驗證。

Radiation angle factor is an important parameter for calculating the radiation heat transfer between human body and radiant panel.In view of the complexity of radiation angle factors between human body and radiant panel,considers the shape of a standing human body as a cuboid to calculate radiation angle factors.Takes the radiant ceiling for example,establishes basic mathematical expressions of radiation angle factor between human body and radiant panel by using contour integral method and algebraic method,and verifies the reasonability of the results.
