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 $var element = document.getElementById("moose-equation-bbb21fe4-fa75-4f59-a9a1-e9a680966a73");katex.render(" \\rho = \\rho_{0}\\exp(P/K_{f} - \\alpha_{f} T),", element, {displayMode:true,throwOnError:false});$ where $var element = document.getElementById("moose-equation-ea8c2ff9-bfca-4e8a-b9e9-a4772ff4bbca");katex.render("K_{f}", element, {displayMode:false,throwOnError:false});$ (the bulk modulus) and $var element = document.getElementById("moose-equation-956ff97e-7c8b-4f79-a007-ad61067642e7");katex.render("\\alpha_{f}", element, {displayMode:false,throwOnError:false});$ (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 $var element = document.getElementById("moose-equation-3ae3eb08-9811-4508-8bd4-f14e078d929a");katex.render(" e = c_v T", element, {displayMode:true,throwOnError:false});$ and $var element = document.getElementById("moose-equation-34b36632-daba-4169-8e1a-8f7a99694404");katex.render(" h = e + \\gamma\\frac{p}{\\rho}", element, {displayMode:true,throwOnError:false});$ respectively. Here $var element = document.getElementById("moose-equation-cb1830c1-ef39-4fec-b9a3-5017232512df");katex.render("\\gamma", element, {displayMode:false,throwOnError:false});$ is called the porepressure_coefficient: usually it should be set to $var element = document.getElementById("moose-equation-4241495c-7400-4011-b01a-9c4a557aca5a");katex.render("1", element, {displayMode:false,throwOnError:false});$ but many analytical studies assume $var element = document.getElementById("moose-equation-0e514b2d-935e-4f83-9848-e8348a61c3d2");katex.render("\\gamma=0", element, {displayMode:false,throwOnError:false});$ .
