IdealGasFluidProperties
These fluid properties implement the ideal gas law:
where
is pressure,
is specific volume,
is the universal gas constant,
is the temperature (in absolute units), and
is the molar mass.
The specific heats (isobaric, , and isochoric, ) are assumed constant, and thus their ratio is constant as well:
The specific internal energy is computed as
where is a reference specific internal energy value (corresponding to ).
The dynamic viscosity and thermal conductivity are assumed constant, though this assumption could later be dropped.

#
# Initially the fluid and heat structures are at rest at ambient conditions,
# and the shaft speed is zero.
# The transient is controlled as follows:
# * 0 - 2000 s: Motor increases shaft speed to approx. 85,000 RPM by PID control
# * 1000 - 8600 s: Power in main heat source increases from 0 - 104 kW
# * 2000 - 200000 s: Torque supplied by turbine increases to steady state level
# as working fluid temperature increases. Torque supplied by
# the motor is ramped down to 0 N-m transitioning shaft control
# to the turbine at its rated speed of 96,000 RPM.

# Navier-Stokes (or Euler) flow of an ideal gas over a step.
#
# Note: this problem is not currently a regression test for the
# Navier-Stokes module since it is in some sense ill-posed. As
# discussed in [0], the sharp corner of the step (both forward and
# backward-facing) introduces a singularity in the first derivative of
# the velocity and pressure fields, and therefore produces large
# numerical errors in the neighborhood of these points. Physically,
# this numerical error can be interpreted as causing an artificial
# "boundary layer" to form just above the step, as well as a spurious
# production of entropy even though the flow remains subsonic.
# Nevertheless, the forward-facing step problem in particular remains
# a challenging and well-document test problem for flow solvers, and
# this input file is included to help facilitate its development and
# employment by users of the module.

# 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
# and thus density is
# rho = 0.27346825980066236 kg/m^3

# Tests that energy conservation is satisfied in 1-phase flow when there are
# multiple heat structures are connected to the same pipe.
#
# This problem has 2 heat structures with different material properties and
# initial conditions connected to the same flow channel, which has solid wall
# boundary conditions at both ends. An ideal gas equation of state is used for
# the fluid:
# e(T) = cv * T
# From energy conservation, an analytic expression for the steady-state
# temperature results:
# (rho(p,T)*e(T)*V)_fluid + (rho*cp*T*V)_hs1 + (rho*cp*T*V)_hs2 = constant
# The following are constant:
# V_i domain volumes for flow channel and heat structures
# rho_fluid fluid density (due to conservation of mass)
# rho_hsi heat structure densities
# cp_hsi heat structure specific heats
# Furthermore, all volumes are set equal to 1. Therefore the expression for the
# steady-state temperature is the following:
# T = E0 / C0
# where
# E0 = (rho(p0,T0)*e(T0))_fluid + (rho*cp*T0)_hs1 + (rho*cp*T0)_hs2
# C0 = (rho(p0,T0)*cv)_fluid + (rho*cp)_hs1 + (rho*cp)_hs2
#
# An ideal gas is defined by (gamma, R), and the relation between R and cv is as
# follows:
# cp = gamma * R / (gamma - 1)
# cv = cp / gamma = R / (gamma - 1)
# For the EOS parameters
# gamma = 1.0001
# R = 100 J/kg-K
# the relevant specific heat is
# cv = 1e6 J/kg-K
#
# For the initial conditions
# p = 100 kPa
# T = 300 K
# the density and specific internal energy should be
# rho = 3.3333333333333 kg/m^3
# e = 300000000 J/kg
#
# The following heat structure parameters are used:
# T0_hs1 = 290 K T0_hs2 = 310 K
# rho_hs1 = 8000 kg/m^3 rho_hs2 = 6000 kg/m^3
# cp_hs1 = 500 J/kg-K cp_hs2 = 600 J/kg-K
#
# E0 = 1e9 + 8000 * 500 * 290 + 6000 * 600 * 310

# C0 = 3.3333333333333e6 + 8000 * 500 + 6000 * 600

# Euler flow of an ideal gas over a Gaussian "bump".
#
# The inlet is a stagnation pressure and temperature BC which
# corresponds to subsonic (M=0.5) flow with a static pressure of 1 atm
# and static temperature of 300K. The outlet consists of a
# weakly-imposed static pressure BC of 1 atm. The top and bottom
# walls of the channel weakly impose the "no normal flow" BC. The
# problem is initialized with freestream flow throughout the domain.
# Although this initial condition is less physically realistic, it
# helps the problem reach steady state more quickly.
#
# There is a sequence of uniformly-refined, geometry-fitted meshes
# from Yidong Xia available for solving this classical subsonic test
# problem (see the Mesh block below). A coarse grid is used for the
# actual regression test, but changing one line in the Mesh block is
# sufficient to run this problem with different meshes. An
# entropy-based error estimate is also provided, and can be used to
# demonstrate convergence of the numerical solution (since the true
# solution should produce zero entropy). The error should converge at
# second-order in this norm.
