SimpleFluidProperties

Fluid properties for a simple fluid with a constant bulk density

This is a computationally simple fluid based on a constant bulk modulus density fluid, with density given by ρ=ρ0exp(P/KfαfT), \rho = \rho_{0}\exp(P/K_{f} - \alpha_{f} T), where KfK_{f} (the bulk modulus) and αf\alpha_{f} (the thermal expansion coefficient) are constants.

In this formulation, viscosity and thermal conductivity are constant (with values specified in the input file), while internal energy and enthalpy are given by e=cvT e = c_v T and h=e+γpρ h = e + \gamma\frac{p}{\rho} respectively. Here γ\gamma is called the porepressure_coefficient: usually it should be set to 11 but many analytical studies assume γ=0\gamma=0.
