| Abstract: | Through numerical simulation, the bubble oscillation and expansion behavior during its rising in fuel oil with thermal stratification have been studied in this paper. The influence of fuel oil viscosity and thermal stratification on the bubble dynamic behavior also have been studied in detail. Some results with reasonable physical trends have been obtained. |
