After observing the abrupt variations in flow on an aerodynamic model having the form of a conventional valve, modifications in the basic geometry of the valve are proposed in order to stabilize the flow. The instabilities are almost completely eliminated by introducing an exergy-destructive element into the design of the valve head and seat.
