Abstract
An example gas turbine engine airfoil includes an airfoil wall establishing a cavity that extends axially from an airfoil leading edge portion to an airfoil trailing edge portion and extends radially from an airfoil inner end to an airfoil outer end. The cavity is configured to receive a baffle that is spaced from the airfoil leading edge portion such that an impingement cooling area is established between the airfoil leading edge portion and the baffle when the baffle is received within the cavity. An array of nonuniformly distributed features is disposed on the airfoil wall within the impingement cooling area. The features are configured to influence airflow within the impingement cooling area.
