Chondrules suggest that there were some flash heating events to form chondrules in the early solar nebula. Shock wave heating model is considered to be one of the most plausible models for chondrule formation.
In the shock-wave heating model, dust particles are heated by the gas frictional heating. So it is easily expected that the dust particle start to melt from its surface to inside. Additionally, due to the ram pressure of the fast gas flow, the liquid part is considered to strip off from the solid part (Kadono and Arakawa 2005, Kato et al.2006)
In order to examine the thermal evolution and the dynamics of the dust particle, we are developing a numerical code that can solve hydrodynamics inside the dust particle containing solid, liquid, and gaseous phases simultaneously. Here, we report the current status of the development and the future plan of our research.
