Abstract : There is considered the nonadiabatic dispersion of a plane layer of gas of assigned mass M in a vacuum taking into account gradual energy release according to a given law. It is shown that with several initial profiles of distribution of parameters the variables are divided. Usual differential equations are solved for determination of the relationship of characteristic pressure, density and velocity to time for initially resting cold gas. The asymptotic power law of change of parameters, establishing energy release with prolonged time in comparison with characteristic gas-dynamic for energy release constant in time pressure, density and velocity is found. There is determined the pulse, affecting a hard surface, limiting the layer of gas on one side during energy release and time of subsequent adiabatic or isothermal dispersion. (Author)
