Abstract
Impingement assemblies and components of gas turbine engines are described. The impingement assemblies include an impingement plate having a plurality of impingement holes formed therein and an impingement surface arranged relative to the impingement plate with an impingement cavity defined between the impingement plate and the impingement surface. A raised wall is configured on the impingement surface and extends in a direction from the impingement surface toward the impingement plate and defines a plurality of impingement cells each having a geometric shape on the impingement surface.
