LinearFVScalarAdvection

This kernel adds the contributions of the scalar advection term to the matrix and right hand side of the scalar equation system for the finite volume SIMPLE segregated solver SIMPLE.

This term is described by $var element = document.getElementById("moose-equation-8098b730-50ed-4ec7-bc94-72fe616c01d9");katex.render("\\nabla \\cdot \\left(\\vec{u} C_i \\right)", element, {displayMode:false,throwOnError:false});$ present in the scalar equation conservation for an incompressible/weakly-compressible formulation.

For FV, the integral of the advection term of scalar $var element = document.getElementById("moose-equation-90366755-7c71-4b27-ace4-963d63d337cc");katex.render("C_i", element, {displayMode:false,throwOnError:false});$ over a cell can be expressed as:

$var element = document.getElementById("moose-equation-7d01896d-5552-42a2-bd23-6c02deb27ec6");katex.render("\\int\\limits_{V_C} \\nabla \\cdot \\left(\\vec{u} C_i \\right) dV \\approx \\sum\\limits_f ( \\vec{u}\\cdot \\vec{n})_{RC} C_if |S_f| \\,", element, {displayMode:true,throwOnError:false});$

where $var element = document.getElementById("moose-equation-a166a69f-85ac-4e36-88a6-c7f9a846d9e3");katex.render("C_{if}", element, {displayMode:false,throwOnError:false});$ is the face value of the scalar concentration. An interpolation scheme (e.g. upwind) can be used to compute the face value. This kernel adds the face contribution for each face $var element = document.getElementById("moose-equation-4867b72c-958f-4ade-ba89-ff2ccd168c3a");katex.render("f", element, {displayMode:false,throwOnError:false});$ to the right hand side and matrix.

The volumetric face flux $var element = document.getElementById("moose-equation-b5f71ba5-2f9d-49bc-8361-128a407a18a2");katex.render("(\\vec{u}\\cdot \\vec{n})_{RC}", element, {displayMode:false,throwOnError:false});$ is provided by the RhieChowMassFlux object which uses pressure gradients and the discrete momentum equation to compute face velocities and mass fluxes. For more information on the expression that is used, see SIMPLE.
