riemann::KEEP Struct Reference

Kinetic-energy- and entropy-preserving central flux (KEEP; Kuya, Totani & Kawai, J. Comput. Phys. 375, 2018) with arithmetic means: mass C = mean(rho) mean(u).n, momentum C mean(u) + mean(p) n, energy C (mean(e) + u_L . u_R / 2) + (p_L u_R.n + p_R u_L.n) / 2. Its momentum flux has Jameson's form, so with cell values on both sides the convective fluxes change the kinetic energy only by the pressure work mean(p) (u_R - u_L).n per face. No dissipation: for the hybrid convective flux (docs/design/les.md, section 4.3). More...

Detailed Description

Kinetic-energy- and entropy-preserving central flux (KEEP; Kuya, Totani & Kawai, J. Comput. Phys. 375, 2018) with arithmetic means: mass C = mean(rho) mean(u).n, momentum C mean(u) + mean(p) n, energy C (mean(e) + u_L . u_R / 2) + (p_L u_R.n + p_R u_L.n) / 2. Its momentum flux has Jameson's form, so with cell values on both sides the convective fluxes change the kinetic energy only by the pressure work mean(p) (u_R - u_L).n per face. No dissipation: for the hybrid convective flux (docs/design/les.md, section 4.3).
