This article describes a semi-empirical equation that can be used to assess radiation heat transfer in terms of an effective convection coefficient. The effective convection coefficient due to radiation is shown to be: Where temperatures are in °C and ε is the emissivity of the radiating surface. This equation is accurate to within ~10% over a temperature range of 0 - … [Read more...]
