The final flux function derived in this model is a combination of a gas-kinetic Lax‐Wendroff flux of viscous advection equations and kinetic flux vector splitting. These two basic schemes are coupled through a non-linear gas evolution process and it is found that this process always ...

WebSep 29, 2016 · In this paper we develop a novel two-stage fourth order time-accurate discretization for time-dependent flow problems, particularly for hyperbolic conservation laws. Different from the classical Runge--Kutta (R--K) temporal discretization for first order Riemann solvers as building blocks, the current approach is solely associated with Lax- … WebGas-kinetic schemes based on the BGK model are proposed as an alternative evolution model which can cure some of the limitations of current Riemann solvers. To analyse the …
WebSep 15, 2024 · In this paper, a high-order multi-dimensional gas-kinetic scheme is presented for both inviscid and viscous flows in arbitrary Lagrangian-Eulerian (ALE) formulation. Compared with the traditional ALE method, the flow variables are updated in the finite volume framework, and the rezoning and remapping steps are not required. WebJun 10, 2004 · In fact, a kinetic solution with the collision effect yields the Lax–Wendroff-type scheme in the case of piecewise-linear reconstruction with smoothness at cell interfaces [10], [13], i.e. the simple connection of cell-averaged values, and the part of the numerical flux corresponding to the collision effect removes an excess of the numerical …
