Abstract The model of cylindrical blackbody cavity is established, based on the integral equation method,finite element analysis method, Monte-Carlo method , the effective emissivity of blackbody cavity is calculated, and comparison and analysis the different cavity geometry, cavity material emissivity , the probe distance from mouth cavity and other factors have impact on the effective emissivity of the blackbody cavity. The results show that under the same cavity length to diameter ratio, the aperture ratio, material emissivity and other conditions, namely the length to diameter is larger, the aperture ratio smaller, the cavity material emissivity larger then the blackbody cavity have larger effective emissivity.
