Abstract

LES of turbulent combustion has emerged as a practical tool in the simulation of complex industrial combustors. Most combustion models use the mixture-fraction to track reactions. A robust and consistent numerical scheme for suiving the conserved scalar transport equation is thus of paramount importance. Due to inherent numerical instabilities in the advection component of the equation, currently used methods like the QUICK scheme use an upwind-biased stencil to reduce numerical oscillations. It is observed that such schemes can lead to local values that are outside the physical bounds of the scalar. Here a correction scheme is proposed for the QUICK scheme such that physical bounds are exactly maintained in the simulation domain. It is further shown that the Bounded QUICK (BQUICK) scheme performs betters than a third-order total-variation bounded (TVB) scheme in maintaining spatial accuracy and reducing dispersion errors.
