Hello.

Check this schematics of CFM56 as example: http://farm1.static.flickr.com/55/135132177_4b9ec7297f.jpg
AS you can see, inlet is divergent, but compressor is convergent.

aim there is to slow air and increase pressure, making it easy to process and also if air gets faster, fan blades can achieve supersonic speed which doesnt wanted.
