PCNSFVKT
Computes the residual of advective term using finite volume method.
Overview
This object implements the Kurganov-Tadmor (Kurganov and Tadmor, 2000) (KT) scheme for computing inter-cell advective fluxes for the Euler equations. We will outline some of the important equations below, drawing from (Greenshields et al., 2010). The KT flux is a second-order generalization of the Lax-Friedrichs flux. For a given face it can be written as
(1)
where represents the vector of advected quantities, and
where is the porosity, where , , and are the component particle velocities, and is the normal vector pointing from to . This definition of is slightly different from that in (Greenshields et al., 2010) in that it does not contain the face area. This is because here we are essentially describing the implementation in PCNSFVKT while area multiplication happens in the base class FVFluxKernel. is defined as
where
where is the locally computed speed of sound. The default method when computing and is Kurganov, Noelle, Petrova (Kurganov et al., 2001) (KNP) since it's reported (Greenshields et al., 2010) as being less diffusive (enabling sharper front capturing) than the KT method of computing and . is given by
Interpolation of is described in Limiters.
