ThermalDiffusivityFunctorMaterial

Computes the thermal diffusivity given the thermal conductivity, specific heat capacity, and fluid density.

Overview

The ThermalDiffusivityFunctorMaterial object computes the thermal diffusivity

$var element = document.getElementById("moose-equation-ba0fc1c2-337b-465c-963a-9f66170665f1");katex.render("\\alpha = \\frac{k}{\\rho c_p}", element, {displayMode:true,throwOnError:false});$

where $var element = document.getElementById("moose-equation-a6999b93-61da-439f-afed-6363d28e66f0");katex.render("k", element, {displayMode:false,throwOnError:false});$ is the thermal conductivity, $var element = document.getElementById("moose-equation-2369b4f1-a7f2-4df8-b827-92091eb94d9b");katex.render("\\rho", element, {displayMode:false,throwOnError:false});$ is the density, and $var element = document.getElementById("moose-equation-dab8cff4-7272-4e24-8ff1-ce66f994f6c2");katex.render("c_p", element, {displayMode:false,throwOnError:false});$ is the constant-pressure specific heat capacity. Thermal diffusivity has units of length squared over time and is the heat transport analog of the kinematic viscosity in momentum transport and the diffusion coefficient in species/mass transport. This object takes $var element = document.getElementById("moose-equation-5a0bab95-eff4-4763-ac9a-cf7f9774ba40");katex.render("k", element, {displayMode:false,throwOnError:false});$ , $var element = document.getElementById("moose-equation-88df1768-d609-4204-b63a-3d7be26ef609");katex.render("\\rho", element, {displayMode:false,throwOnError:false});$ , and $var element = document.getElementById("moose-equation-de255c24-216e-401c-bab3-47a5a714abe6");katex.render("c_p", element, {displayMode:false,throwOnError:false});$ as input functors and produces $var element = document.getElementById("moose-equation-8e322ea8-b1b0-471f-8b33-241a165cca0c");katex.render("\\alpha", element, {displayMode:false,throwOnError:false});$ as an output functor which will be evaluated on-demand.
