Steady and unsteady flame propagation in a premixed counterflow

Abstract

In this paper we investigate numerically the influence of heat loss and strain rate on the edges of premixed flames in a two-dimensional counterflow. This work represents a continuation and extension of recent work on the topic. Both steady and non-steady edge behaviour is investigated for certain values of the parameters representing heat loss and strain rate in the governing equations. Combustion waves between strongly and weakly burning flames are also investigated.

Keywords:

• Premixed counterflow
• Heat loss
• Flame tubes
