Results of large-scale experiments on the thermal effect from deflagra
tions and detonations in rich fuel-air heterogeneous mixtures are pres
ented. Motor fuels (gasoline, kerosene and diesel fuel) were used. The
fuel mass in the tests was varied from 0.1 to 100 tonnes. The relatio
nships for the maximum fireball radius, heat effect duration and total
emitted energy versus the fuel mass were determined for this kind of
process. Direct measurements of the heat pur and integral heat flux we
re carried out. Comparison with published data for other fuel types is
made. The presented results may be used for accident analyses in indu
stry and transport. Copyright (C) 1996 Published by Elsevier Science L
