10.1 introduction
In present work the dynamics and heat and mass transfer of vapor bubble in a binary
solution of liquids was studied for significant thermal, diffusion and inertial effect.
Consider a two-temperature model of interphase heat exchange for the bubble liquid.
This model assumes homogeneity of the temperature in phases. The intensity of heat
