Abstract
An efficient time‐accurate algorithm is presented for numerical simulations of low‐Mach number variable density flows in the context of non‐premixed flames. The algorithm is based on a segregated solution formalism in the class of pressure‐correction methods. It shows good conservation properties and returns stable results, regardless of the difference in density between neighboring cells. A simplified Burke–Schumann flame model is used to describe the heat release due to mixing of fuel and oxidizer. The convergence rate of the method is discussed for a 1D channel flow, containing fuel and oxidizer. Copyright © 2008 John Wiley & Sons, Ltd.
