The ignition process of a drop of liquid fuel in the gas phase has been the subject of a significant number of theoretical as well as experimental studies. In view of the complexity of these problems, the various authors have used different approximations to simplify the problem, and in practically all of the studies the ignition process was analyzed in an approximation where the processes of heat and mass transfer in the gas medium were inertialess and in an independent diffusion approximation. In the present study the ignition of a drop near critical conditions is studied with the inertia of the gas medium considered. The correctness of replacing the equations of multicomponent diffusion by the independent diffusion equations which are generally used is also analyzed.
