The extent of fire spread by radiation is delimited by separation distances, required to prevent external fire spread due to excessive radiation heat or falling burning brands. The simplified calculation method uses a series of precalculated tabulated values. Alternatively, a more precise analytical calculation approach can be used. The resolution of the method can determine the required separation distances significantly. This paper evaluates analytical calculation methods and CFD simulations to determine their accuracy of separation distances prediction. The most appropriate are standard analytical calculation methods with sufficient number of evaluation points along the radiating surface.
