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.

# This problem has 2 wall heat flux sources, each with differing parameters.

# energy balance is
# (rho*e*A)^{n+1} = (rho*e*A)^n + dt * [(q1*P1) + (q2*P2)]

# THM file based on https://mooseframework.inl.gov/modules/thermal_hydraulics/tutorials/single_phase_flow/step05.html
# Used to loosely couple THM with SCM
# This is a simple open loop with fixed massflow at the inlet and pressure at the outlet.
# THM sends massflux and temperature at the inlet of the core, and pressure at the outlet of the core
# to subchannel. Subchannel returns total pressure drop of the assembly and total power to THM and THM calculates an
# average friction factor for the core region.

# Outlet: p_out = 100 kPa
# Length: L = 2 m

# Tests the initial condition for mixture density from pressure and temperature.
# This test uses the general vapor mixture fluid properties with steam, air,
# and helium with mass fractions 0.5, 0.3, and 0.2, respectively. The individual
# specific volumes (in m^3/kg) at p = 100 kPa, T = 500 K are:
# steam: 2.298113001
# air: 1.43525
# helium: 10.3855
# For the general vapor mixture, the mixture specific volume is computed as
# v = \sum\limits_i x_i v_i ,
# where x_i is the mass fraction of component i, and v_i is the specific volume
# of component i. Therefore, the correct value for specific volume of the mixture is
# v = 3.65673150050 m^3/kg
