Greetings all, Some time back I ran across a web site that discussed smooth airflow, boundary layer separation and the likes. Cowlings and canopies were discussed and one of the examples happened to show the airflow around and through a scoop like the radiator housing for a P-51. The discussion was not about the scoop but the diagrams showed this profile and included an explanation about what happened due to the shape. It was a 2 dimensional colored drawing.
I have looked for a week now and can't find it again. Does anyone recall seeing this and can you point me to it ? Thanks Kevin N4 10WA
