HeatSourceVolumetric1Phase

Volumetric heat source applied on a flow channel

The volumetric heat source is applied to the 1-phase flow channel volume using a ADOneD3EqnEnergyHeatSource kernel, added to the energy equation (with the $var element = document.getElementById("moose-equation-5e090fec-2e60-478e-9063-b977a7471569");katex.render("\\rho E A", element, {displayMode:false,throwOnError:false,macros:{"\\eqc":"\\,,","\\eqp":"\\,.","\\pd":"\\frac{\\partial #1}{\\partial #2}","\\pr":"\\left(#1\\right)","\\ddt":"\\frac{d #1}{d t}"}});$ variable).
