Calculation and Study of the Integrated Emissivity of Cylindrical cavity
In this paper, the integrated emissivity of isothermal cylindrical cavity is calculated based on ANSYS finite element method at different wall material emissivity and Cavity length, and are compared with the calculation results of the Monte Carlo method, the average absolute deviation is 0.00045. Meanwhile, this paper presents meshing rules of the cavity bottom surface and the cavity mouth surface, it proposes that the cavity mouth surface is regarded as the equivalent radiant surface, and calculates the integrated emissivity of different positions on the equivalent radiant surface, analyzes the influence of the wall material emissivity, cavity length, the position of radius direction.
