Research Abstract

The numerical code of multiphase flow was created and it was applied to the falling metal droplets in a magma ocean. The code can successfully calculate the system including interaction of many droplets in a silicate melt such as fragmentation and coalescence. By applying the calculation results to the whole magma ocean, the time scale of core formation of the earth can be more correctly estimated.
