Advanced Methods to Compute Multiphase Turbulent Reacting Flows

Abstract

AbstractPDF and FDF methods do not require approximations for chemical reactions, which makes them extremely valuable for reacting flow calculations. The performance of these methods depends significantly on the accuracy of simulating small‐scale mixing processes. It is illustrated, in which way models may be developed that simulate mixing for various phases as a multi‐scale process in dependence on different factors. Further developments towards a system of very accurate and (less expensive) simplified methodologies for reacting flow calculations are pointed out.
