Radiative Heat Loss Correction for 3-Body Graphite Calorimeters

Title variants
Languages of publication
For a 3-body Domen-type absorbed-dose graphite calorimeter a refined ordinary differential equation model is developed taking into account the heat loss through radiation from the surface of all three bodies. The new reduced heat transfer coefficients, K_{i}*, i = 1, 2, 3 were defined and the associated calculated heat loss correction factors F_{C}* and F_{C+J}* were determined. The total energy lost by radiation from the core surface was evaluated for both heating and post heating periods as being 31.35% from the total core heat loss (and up to 1.1% from the total energy delivered to the core during the heating time). A new correction factor for heat loss through radiation from the calorimeter bodies' surfaces was introduced and calculated as being k_{SB} ≈ 0.9996.
