Feasibility analysis of neutral stability for shock waves in a nonideal gas flow about a wedge

The feasibility of neutral stability for shock waves in the problem of a real gas flow about a wedge is studied by means of numerical experiments. A shock adiabat for a van der Waals gas is derived; that is, a relationship is found between the wedge and shock wave angles. A vast amount of numerical data is obtained, and some of them are summarized in tables. From these data, one can distinguish wedge flow regimes with neutrally stable shock waves.
