Variable pin fin construction to facilitate compliant cold plates

A device can comprise a plurality of layers stacked and bonded on one another, wherein at least one layer of the plurality of layers comprises: a first active region comprising first pin portions positioned in a first planar arrangement; and a second active region comprising second pin portions positioned in a second planar arrangement, wherein the second planar arrangement is different from the first planar arrangement. The device can also comprise a conformable layer adjacent to at least one of the plurality of layers.

Effects of Downstream Vortex Generators on Film Cooling a Flat Plate Fed by Crossflow

This presentation describes experimental and CFD results of a novel idea to improve film cooling effectiveness. This concept involves downstream vortex generators to control counter-rotating vortices that can degrade discrete film cooling jets. The performance can be influenced significantly by how the coolant is supplied to the film cooling holes. In this paper, the effects of a coolant supply channel that is normal to the hot gas path are investigated and discussed.
