Instantaneous and time averaged flame temperatures ¯T , surface emissive power SEP and time averaged irradiances ¯E of di-tert-butyl peroxide (DTBP) pool fires with d = 1.12 m and 3.4 m are investigated experimentally and by CFD simulation. Predicted centerline temperature profiles for d = 1.12 m are in good agreement with the experimental emission temperature profiles for x/d > 0.9. For d = 3.4 m the CFD predicted maximum centerline temperature at x/d = 1.4 is 1440 K whereas the emission temperature experimentally determined fromthermograms at x/d ≈ 1.3 is 1560 K. The predicted surface emissivepower for d = 1.12m is 115kW/m2 in comparison to the measured surface emissive power of 130 kW/m2 whereas for d = 3.4 m these values are 180 and 250 kW/m2. The predicted distance dependent irradiances agree well with the measured irradiances.
