Abstract
A transition piece assembly for a gas turbine includes a transition duct having one end adapted for connection to a gas turbine combustor and an opposite end adapted for connection to a first turbine stage, and a pair of side panels. The assembly also includes an impingement sleeve surrounding the transition duct and establishing a cooling path therebetween. The impingement sleeve is formed with a plurality of rows of cooling holes therein; and a plurality of flow catcher devices on an external surface of the impingement sleeve, each flow catcher device at least partially surrounding one of the cooling holes.
