A bubble nucleation-growth process was investigated in a decompressed Lennard-Jones fluid using an NVT ensemble molecular dynamics simulation. As was reported in an NVE ensemble simulation, a competitive growth similar to Ostwald ripening was also observed in this simulation. On the other hand, more bubble nuclei were formed than those in the NVE ensemble and the growing/shrinking speed of each bubble nucleus became slower due to the temperature control. In this paper, the growth exponent for the mean radius of bubble nuclei was also evaluated, and it was confirmed that the value of the exponent became smaller than that in the NVE ensemble, at least in the present time scale.
