摘要
采用工程计算方法得到最大对流系数并在平板结构有限元模型背面中施加对流边界条件,在平板结构有限元模型热面中施加空间辐射边界条件,通过热流反演得到平板结构所需要的最大热流,最后根据平板面积计算得到其加热功率。
The maximum convective coefficient is obtained by engineering calculation method,and the convective boundary condition is applied in the back of the finite element model of the flat plate structure,and the space radiation boundary condition is applied to the hot surface of the finite element model of the flat plate structure.The maximum heat flow required by the flat plate structure is obtained by heat flow inversion.Finally,the heating power is calculated according to the plate area.
