Shock-Capturing and Front-Tracking Methods for Granular Avalanches [PDF]

open access: yesJournal of Computational Physics, 2002
Shock formations are observed in granular avalanches when supercritical flow merges into a region of subcritical flow. In this paper we employ a shock-capturing numerical scheme for the one-dimensional Savage-Hutter theory of granular flow to describe this phenomenon. A Lagrangian moving mesh scheme applied to the non-conservative form of the equations

Improving the quantification of overshooting shock-capturing oscillations [PDF]

open access: yes, 2023
An approach for quantitatively evaluating overshooting oscillations is designed to characterize the performance of shock-capturing schemes. Specifically, following our previous work focused on cases with only discontinuities, now we account for the ...

A brief review on the convergence to steady state solutions of Euler equations with high-order WENO schemes

open access: yesAdvances in Aerodynamics, 2019
Weighted essentially non-oscillatory (WENO) schemes are a class of high-order shock capturing schemes which have been designed and applied to solve many fluid dynamics problems to study the detailed flow structures and their evolutions.

Shock Capturing in Large Eddy Simulations by Adaptive Filtering

open access: yesFluids, 2019
A method for shock capturing by adaptive filtering for use with high-resolution, high-order schemes for Large Eddy Simulations (LES) is presented. The LES method used in all the examples here employs the Explicit Filtering approach and the spatial ...

Angiotensin II in the treatment of distributive shock: a systematic-review and meta-analysis. [PDF]

open access: yes
BACKGROUND While non-norepinephrine vasopressors are increasingly used as a rescue therapy in cases of norepinephrine-refractory shock, data on their efficacy are limited.

Preserving stationary discontinuities in two-layer shallow water equations with a novel well-balanced approach

open access: yesJournal of Hydroinformatics, 2023
This paper proposes a novel energy-balanced numerical scheme for the two-layer shallow water equations (2LSWEs) that accurately captures internal hydraulic jumps without introducing spurious oscillations. The proposed scheme overcomes the problem of post-
