SodiumSaturationFluidProperties

Fluid properties for liquid sodium at saturation conditions

Description

The SodiumSaturationFluidProperties class provides fluid properties for _saturated_ liquid sodium based on correlations used in the SAS4A/SASSYS-1 reactor dynamics and safety analysis code developed at Argonne National Laboratory for liquid metal reactors Dunn (2017). These property models are obtained as fits to experimental data, with computational efficiency motivating the use of a simpler functional fits than proposed in the original references upon which the SAS4a/SASSYS-1 implementation is based, namely Fink and Leibowitz (1979). Only for $var element = document.getElementById("moose-equation-5c877f6e-af2e-4de3-bfd1-759616e352d5");katex.render("C_p", element, {displayMode:false,throwOnError:false});$ and $var element = document.getElementById("moose-equation-3ffa2b9a-c235-4bcc-84ee-eb2ecbf96fdf");katex.render("C_v", element, {displayMode:false,throwOnError:false});$ are the original correlations/data used, since the SAS4A/SASSYS-1 implementation does not differentiate between $var element = document.getElementById("moose-equation-9990cf49-f763-4165-a0f7-cf1da8433ce0");katex.render("C_p", element, {displayMode:false,throwOnError:false});$ and $var element = document.getElementById("moose-equation-f0f510a5-41a6-49cf-ac47-59835046a081");katex.render("C_v", element, {displayMode:false,throwOnError:false});$ for the saturated liquid.

Density is calculated as an empirical fit to two saturated liquid density correlations recommended by Fink and Leibowitz that cover the range $var element = document.getElementById("moose-equation-128d5102-3dd9-4de8-bf81-6b73e4174399");katex.render("371 < T (K) < 2509", element, {displayMode:false,throwOnError:false});$ :

$var element = document.getElementById("moose-equation-1ada2a71-8d8f-4747-b3b0-a68e7e33dbde");katex.render("\\rho=1.00423\\times10^3-0.21390T-1.1046\\times10^{-5}T^2", element, {displayMode:false,throwOnError:false});$

This equation fits the Fink and Leibowitz models to within 9.5%.

The thermal conductivity is a fit to experimental data by Fink and Leibowitz below 1500 K, and extrapolated values above 1500 K based on a method described by Grosse Dunn (2017):

$var element = document.getElementById("moose-equation-f6b48bc9-a821-4f5c-be83-06ab7330c51e");katex.render("k=1.1045\\times10^2-6.5112\\times10^{-2}T+1.5430\\times10^{-5}T^2-2.4617\\times10^{-9}T^3", element, {displayMode:false,throwOnError:false});$

This equation fits the Fink and Leibowitz data to within 0.5%.

The dynamic viscosity is given as a fit to experimental data by Fink and Leibowitz below 1200 K and extrapolated values about 1200 K based on a method described by Grosse Dunn (2017):

$var element = document.getElementById("moose-equation-18757995-74d9-4d77-9840-d8bcd72752f8");katex.render("\\mu=3.6522\\times10^{-5}+\\frac{0.16626}{T}-\\frac{4.56877\\times10^1}{T^2}+\\frac{2.8733\\times10^4}{T^3}", element, {displayMode:false,throwOnError:false});$

This equation fits the Fink and Leibowitz data to within 0.5%.

The isobaric and isochoric specific heats are obtained as new fits to the experimental data in Fink and Leibowitz over the range $var element = document.getElementById("moose-equation-3ba77b94-e7f1-43b9-af39-b225cc89dab5");katex.render("400 < T (K) < 2200", element, {displayMode:false,throwOnError:false});$ ,
