Gas Channel Formation Studies Including Real-Air Thermodynamic Properties
Abstract
Real-air thermodynamic properties are included in studies of reduced density channel formation by expansion of a heated cylinder of air. A model for density profile at late times, previously given for a polytropic ideal gas, is extended to the present case. It is shown that a relation between pressure P, density rho, and specific energy epsilon, of the form properties. The variation of f with epsilon, i.e. of specific heat with temperature, can strongly modify the initial pressure profile associated with a given energy density profile. The effects of real-gas thermodynamics during the hydrodynamic expansion, on the other hand, are rather weak.
