Abstract
In this paper we explore the specification of time dependent boundary conditions for the simulation of low Mach number reacting flows. A new approach is presented which is derived from the method of characteristics and an application of a Mach number based double expansion. Through the double expansion, it is possible to identify and seperate inertial events from acoustic events. By controlling the inertial components of the flow, non-reflecting conditions for a wide variety of problems may be specified. The accuracy of the method is demonstrated using a curved stagnating flame, in which the reaction zone crosses the boundary.
