Numerical prediction of safety distances from large pool fires of organic peroxides

  • Organic peroxides are energetic substances liable to decompose due to exothermic reactions when exposed to uncontrolled temperature, contamination, confinement and quantity. Their safe storage and transportation are the prime concern and chemical industries and regulating authorities. Their accidental release may and most often lead to shape of a pool. In present study, safety distances from such large pool fires (diameter d = 3.4 m) of organic peroxides are numerically predicted by solving the reactive, 3-D time dependent Navier-Stokes equations with reliable assumptions. The present model is validated against the data on buoyant turbulent diffusion flames. The safety distances predicted by simulation assume three regions in a fully developed fire i.e. hot spot, luminous zone and a flame surface. The time averaged data of temperatures of these regions lead to better estimation of irradiances against the measured data.
