Abstract: A seal for a gas turbine engine includes a first seal structure and a second seal structure. The first seal structure is separated from the second seal structure by a gap. The first seal structure includes an injector extending into the gap with an outlet that is in fluid communication with a fluid source. Fluid issuing from the outlet and against the second seal structure magnifies a vortex formed within the gap by fluid traversing the gap.
