Blowdown and Charging Processes in a Single Gas Receiver With Heat Transfer

Gas blowdown and charging processes are generally analyzed on the basis of an adiabatic thermodynamic process. In most such processes of technical interest there is a considerable amount of heat transfer between the gas and the container walls, and in some applications heat capacitors are deliberately inserted in the container to control temperature or store thermal energy. In this paper the general problem of blowdown and charging is considered, including the effects of heat transfer to or from container walls or inserted heat capacitors. An experimental investigation of blowdown with heat transfer is described, and it is shown that the results correspond very well with the analysis.
