Abstract
An example turbine component cooling arrangement includes a film plate having a plurality of film channels extending from film channel entrances on a first side of the film plate to corresponding film channel exits on an opposing second side of the film plate. The arrangement also includes an impingement plate establishing a plurality of impingement channels. The impingement plate is spaced a distance from the film plate. The plurality of impingement channels are configured to direct a fluid across the distance to contact the film plate between adjacent ones of the film channel entrances. In one example, the distance from the film plate to the impingement plate is between two and four times more than diameter of one of the impingement channels.
