摘要：

Initially uniform clouds of fuel particulates in air sustain processes which may lead to particle-cloud nonuniformities. In low gravity, flame-induced Kundt's tube phenomena are observed to form regular patterns of nonuniform particle concentrations. Irregular patterns of particle concentrations also are observed to result from selected nonuniform mixing processes. Low-gravity flame propagation for each of these classes of particle-cloud flames has been found to depend importantly on the flame-generated infrared radiative fields. The spatial structures of these radiative fields are described. Application is made for the observed cases of lycopodium-air flames.
