A low diﬀusive ﬂux diﬀerence splitting based kinetic scheme is developed based on a discrete velocity Boltzmann equation, with a novel three velocity model. While two discrete velocities are used for upwinding, the third discrete velocity is utilized to introduce appropriate additional numerical diﬀusion only in the expansion regions, identiﬁed using relative entropy (Kullback-Liebler divergence) at the cell-interface, along with the estimation of physical entropy. This strategy provides an…

When approximating a hyperbolic system of conservation laws w t + {f(w)} t = 0 with so-called upwind differences, one must determine in which direction each of a variety of signals moves through the computational grid.

The flow of a gas in a shock tube is treated in the context of kinetic theory as an initial value problem for the one‐dimensional Krook equation. The only simplifying assumption made is that the gas…
