1. A combustor liner for a gas turbine comprising:
a cold side liner segment including a plurality of cold side cooling airflow openings therethrough;
a hot side liner segment arranged inward of the cold side liner segment and including a plurality of hot side cooling airflow openings therethrough;
a baffle cavity defined between a first side of the cold side liner segment and a first side of the hot side liner segment; and
at least one cooling airflow dispersing member arranged within the baffle cavity, the at least one cooling airflow dispersing member including a main cavity portion, and a plurality of peripheral cavity portions surrounding the main cavity portion, the main cavity portion including (i) a main cavity wall defining a main cavity wall perimeter, (ii) a main cavity inlet side having at least one of the plurality of cold side cooling airflow openings, (iii) a main cavity outlet side for providing an impingement cooling to a portion of the hot side liner segment, and (iv) at least one peripheral cavity outlet flow passage providing fluid communication between the main cavity portion and at least one of the plurality of peripheral cavity portions, and the plurality of peripheral cavity portions including a first peripheral cavity portion having a first peripheral cavity wall defining a first peripheral cavity wall perimeter surrounding the main cavity wall perimeter of the main cavity wall with a first gap therebetween, and a second peripheral cavity portion having a second peripheral cavity wall defining a second peripheral cavity wall perimeter surrounding the first peripheral cavity wall perimeter with a second gap therebetween, the first peripheral cavity portion and the second peripheral cavity portion including a peripheral cavity outlet side having at least one of the plurality of hot side cooling airflow openings therethrough.
