Combined effects of heat loss and curvature on turbulent flame-wall interaction in a premixed dimethyl ether/air flame

Autor: Kaddar, Driss, Steinhausen, Matthias, Zirwes, Thorsten, Bockhorn, Henning, Hasse, Christian, Ferraro, Federica

This study investigates the effects of curvature on the local heat release rate and mixture fraction during turbulent flame-wall interaction of a lean dimethyl ether/air flame using a fully resolved simulation with a reduced skeletal chemical reactio

Report

Flame-vortex interaction during turbulent side-wall quenching and its implications for flamelet manifolds

Autor: Steinhausen, Matthias, Zirwes, Thorsten, Ferraro, Federica, Scholtissek, Arne, Bockhorn, Henning, Hasse, Christian

Publikováno v: Proceedings of the Combustion Institute (2022)

In this study, the thermochemical state during turbulent flame-wall interaction of a stoichiometric methane-air flame is investigated using a fully resolved simulation with detailed chemistry. The turbulent side-wall quenching flame shows both head-o

Report

Modelling the response of a turbulent jet flame to acoustic forcing in a linearized framework using an active flame approach

Autor: Kaiser, Thomas Ludwig, Varillon, Gregoire, Polifke, Wolfgang, Zhang, Feichi, Zirwes, Thorsten, Bockhorn, Henning, Oberleithner, Kilian

This study performs a linear analysis of a turbulent reacting methane-air jet flame, with the goal of predicting the response of the reacting flow to upstream acoustic actuation. Accounting for heat release fluctuations is a vital component when inve
