Abstract
Turbines (jet engines or gasturbines) have rotors at the hot end that need to be cooled. This cooling is done by blowing cool air through the blade (internal cooling) or through holes in the surface (to provide for film cooling). A variety of methods is used to drill these holes (electrochemistry or laser drilling), Simulation of the flow eventually provides for a complex problem that is tackled by a domain decomposition technique.
