WebFeb 1, 2024 · The linearized stability analysis of the TV flux splitting scheme reveals that all perturbations in the streamwise direction, or longitudinal direction, are attenuated while the perturbations of density and shear velocity in the transverse direction are unattenuated. WebThe Lax–Friedrichs method, named after Peter Lax and Kurt O. Friedrichs, is a numerical method for the solution of hyperbolic partial differential equations based on finite differences. The method can be described as the FTCS (forward in time, centered in space) scheme with a numerical dissipation term of 1/2. WebThis paper presents a new flux splitting scheme for the Euler equations. The proposed scheme termed TV-HLL is obtained by following the Toro-Vazquez splitting (Toro and Vázquez-Cendón, 2012) and using the HLL algorithm with modified wave speeds for the pressure system.
