Abstract
The paper reports on an investigation of heat transfer and flow field in a model combustor to study self-excited oscillations. This burner (referred to as LIMOUSINE burner) consists of a triangular bluff-body placed in a rectangular channel with variable section and adjustable acoustic inlet and outlet boundaries. Due to its geometry, self-excited oscillations of the pressure field occur in the burner as result of the closed feedback between acoustics and combustion. The numerical simulations focus on the prediction of unsteady heat flux during thermoacoustic oscillations, in order to show its changes as a consequence of the response of the thermal boundary layer.
