An Overall Correlation of Film Cooling Effectiveness From One Row of Holes [PDF]
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 1997 Film cooling effectiveness of a single row of cylindrical holes on a flat plate was analyzed. It was found, that the flow can be divided into two typical regimes along the downstream distance. Near the ejection location a complex flow domain of cooling film formation with strong 3-D character was recognized.
