In order to investigate the dynamic characteristics of a bubble induced by the interaction between a hot residue and water from the underwater combustion of pyrotechnic composition, the heat transfer and mass transfer model of a bubble containing a hot residue is established. The bubble radius and its growth rate are calculated, and bubble radius calculated and the literature results were compared, effects of the hot residue characteristics on bubble dynamics are analyzed. Results show that with the high temperature residue continuous cooling,although bubble radius increases constantly, growth rate becomes slowly, and the calculated results agree well with literature.
