文摘

This year, 2013, marks the 40th anniversary of the journal article ¡°Flux-Corrected Transport I. SHASTA, A Fluid Transport Algorithm That Works¡± by Jay Boris and David Book . Flux-Corrected Transport (FCT) removed a serious roadblock to advances in Computational Fluid Dynamics (CFD) by enabling the accurate treatment of strong, time-dependent shock problems in blast, reactive-flow, and combustion physics, and in aerodynamics and astrophysics. Steep gradients in conserved fluid variables could now be convected across a computational grid without the appearance of spurious oscillations and physically impossible negative values. The nonlinear ¡°flux-correction¡± algorithm introduced in FCT imposes the physical properties of conservation, locality, causality, and monotonicity on the numerical solutions for convection without adding a great deal of numerical diffusion. This article shows that implementing these physical properties in solving the continuity equation through high-resolution FCT also results in a serviceable Large-Eddy Simulation treatment of turbulent flows without need for additional ¡°subgrid turbulence models.¡± We have named this simplified approach Monotone Integrated Large Eddy Simulation (MILES).
