Air velocity, temperature, and radiant-heat measurements within and around a large free-burning fire
Operation Euroka was a 210,000 square m (50 acres) free-burning mass fire experiment carried out in Queensland, Australia. At the peak of the fire, 42 min after ignition, the maximum average induced horizontal wind velocity at the edge of the fire was 4.2 m/see. The fire was of…
