Embedded turbulence model in numerical methods for hyperbolic conservation laws

摘要

The paper describes the use of numerical methods for hyperbolic conservation laws as an embedded turbulence modelling approach. Different Godunov-type schemes are utilized in computations of Burgers' turbulence and a two-dimensional mixing layer. The schemes include a total variation diminishing, characteristic-based scheme which is developed in this paper using the flux limiter approach. The embedded turbulence modelling property of th above methods is demonstrated through coarsely resolved large eddy simulations with and without subgrid scale models.
