A high-efficiency and low-dissipation hybrid weighted essentially non-oscillatory scheme
X. Y. Hu, B. Wang, N. A. Adams
In this paper, we propose a simple hybrid WENO scheme to increase computational efficiency and decrease numerical dissipation. Based on the characteristic-wise approach, the scheme…
A SPH model for incompressible turbulence
X. Y. Hu, N. A. Adams
A coarse-grained particle model for incompressible Navier-Stokes (NS) equation is proposed based on spatial filtering by utilizing smoothed particle hydrodynamics (SPH) approximati…
Low Mach number effect in simulation of high Mach number flow
X. Y. Hu, N. A. Adams
In this note, we relate the two well-known difficulties of Godunov schemes: the carbuncle phenomena in simulating high Mach number flow, and the inaccurate pressure profile in simu…
Dispersion-dissipation condition for finite difference schemes
X. Y. Hu, V. K. Tritschler, S. Pirozzoli +1
A general dispersion-dissipation condition for finite difference schemes is derived by analyzing the numerical dispersion and dissipation of explicit finite-difference schemes. The…
Positivity-preserving flux limiters for high-order conservative schemes
X. Y. Hu, N. A. Adams, C. -W. Shu
In this work a simple method to enforce the positivity-preserving property for general high-order conservative schemes is proposed. The method keeps the original scheme unchanged a…
