Thermal radiation of di-tert-butyl peroxide pool fires - Experimental investigation and CFD simulation
Instantaneous and time averaged flame temperatures anti T, surface emissive power SEP (surface emissive power) and time averaged irradiances anti E of DTBP (di-tert-butyl peroxide) pool fires with d = 1.12 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 (computational fluid dynamics) predicted maximum centerline temperature at x/d=1.4 is 1440 K whereas the emission temperature experimentally determined from thermograms at x/d approx 1.3 is 1560 deg K. The predicted surface emissive power for d=1.12 m is 115 kW/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.
