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 (1) where (the bulk modulus) and (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 (2) and (3) respectively. Here is called the porepressure_coefficient: usually it should be set to but many analytical studies assume .
