An introduction to the field of high temperature gas flows without transport phenomena, electromagnetic phenomena and external forces is presented. The difference between such a flow and the corresponding flow of an ideal gas of constant specific heats comes from internal changes in the fluid. If these changes form a reversible process, the high temperature gas flow as well as the corresponding flow of an ideal gas of constant specific heats belong to the general class of flows of a physically homogeneous medium. The article yields a first understanding of the field and informs about important applications. It describes the real gas model adopted in this article, and various concepts of thermodynamic equilibrium are explained. The close relationship and fundamental differences are demonstrated by means of suitable flow patterns.
