Abstract: A gas outflow numerical simulation into a high density environment by using different variants two-phase medium regime maps and in view of the slip phase has been carried out. The fact of a significant influence of the regime map type at the characteristics of non-stationary gas outflow into a liquid and stationary one has been determinated. In particular it is shown that the transition in the calculations from "dropping" regime map to "bubble-dropping" one there is a significant change in the pressure profile within the channel and in the outer region takes place.
