Abstract
Heat shields and methods of cooling a heat shield are provided. A heat shield of a combustor may be cooled. The heat shield comprises a first surface and a second surface, where the first surface is opposite the second surface, and the first surface is configured to face a combustion chamber. The heat shield may be cooled by directing airflow over the heat shield through channels towards an opening of the heat shield and past turbulators located in the channels.
