why the vortex?

Why is there a vortex on a passenger jet engine when the fans are spinning in reverse but not forwards as normal and is it suckin air through the engine in reverse and blowing it out the front creating the vortex?

Jet engines don’t really run in reverse. To get backwards thrust they use a thrust reverser which is basically a curved scoop behind the engine to throw the air forwards instead of backwards
