An efficient targeted ENO scheme with local adaptive dissipation for compressible flow simulation

High fidelity numerical simulation of compressible flow requires the method being used to have both stable shock-capturing capability and high spectral resolution. Recently, a family Targeted Essentially Non-Oscillatory (TENO) schemes is developed fulfill such requirements. Although TENO has very low dissipation for smooth flow, it introduces cutoff value CT maintain non-oscillatory property. As actually controls property TENO, choice better also means higher small structures. To overcome this, in this paper, new local adaptive proposed CT. By introducing novel function based on WENO smoothness indicators, dynamically adjusted from 1.0×10?10 lower 1.0×10?4 capturing shock according reconstruction stencil. The results are compared with those original an Fu et al. (2019) [49]. It reveals that capable suppressing oscillations near discontinuities while further improving resolution at extra computational cost.
