Sentence examples for order flux from inspiring English sources

In the ADER approach, high order polynomial reconstruction from cell averages is combined with high order flux evaluation, where the latter is done by solving generalized Riemann problems across cell interfaces.

The key idea of this parameterized limiting technique is to limit the high order numerical flux with a first order flux which preserves the MPP or positivity-preserving (PP) property.

In this work we propose a second order flux limiter finite volume method, named PVM-2U-FL, that only uses information of the two external waves of the hyperbolic system.

The scheme works by coupling together a high order flux-based method with a conservative semi-Lagrangian solver that is similar in spirit to that of Lentine et al. [26], but modified to treat the cut cells and partial volumes that arise near a thin solid structure.

A key idea in finite difference weighted essentially non-oscillatory (WENO) schemes is a combination of lower order fluxes to obtain a higher order approximation.

Second, the high-order flux (f^{mathrm{HO}}) is computed component by component.

Of course, the hybridisation of the high-order flux with the Lax-Friedrichs should be activated only in regions of the flow that are problematic.

As a consequence, the high-order flux function takes much more computational time than that of a 2nd-order gas-kinetic scheme.

The technique performed successfully as shown by the ability of the second-order flux to match the prediction of the original transport equations.

The current high-order flux evaluation method is an extension of the second-order gas-kinetic BGK scheme for the Navier Stokes equations (BGK-NS).

On the other hand, in regions where the flow is smooth and away from near vacuum, θ is close to unity, ensuring the use of the high-order flux and preserving the high accuracy of the method.
