Abstract
The present work is concerned with the study of the possibility of creating recirculation zones in inviscid supersonic flows. These regions can be useful, for instance, as flame holders in the case of supersonic combustion devices. The physical model adopted addresses the actual major interest of the present effort, which is to contribute towards the understanding of the origin of a recirculation bubble in an inviscid supersonic channel flow. The flows of interest here can be adequately modeled by the Euler equations in two dimensions. The solution of the system of governing equations is obtained using a total variation diminishing (TVD) method. The physical problem encompasses the analysis of the conditions in which the existence of a recirculation bubble is possible for inviscid supersonic flows. The results exhibit what are the flow and boundary condition combinations necessary to create recirculation bubbles in the flow.
