StiffenedGasFluidProperties

Fluid properties for a stiffened gas

A simple fluid class that implements a stiffened equation of state (Métayer et al., 2004) where is the ratio of specific heat capacities, is a constant that defines the zero reference state for internal energy, and is a constant representing the attraction between fluid molecules that makes the fluid stiff in comparison to an ideal gas. This equation of state is typically used to represent water that is under very high pressure.
