any takers for explaining the toroidal vortex on the allison 250

just want to make sure I am understanding the direction of flow correctly
I am making an animation of the airflow, & whilst I realise that RR have a very neat little CD with an excellent animation. I don't have nor will probably never get my hands on a copy as much of the other content on the CD is for LAME's only.
the animation I am making is a very simplified 'dummies guide' for new pilots making the transition from piston to their first turbine (usually a jetty - so i picked the 250)
thanks in advance.
cheers
