I hope this thread is not too remedial, but I will try. For the pressure based solver in Fluent, it seems to be a 'transient' SIMPLE type method with BDF2 integration. Using SIMPLE makes sense for steady computations, but not unsteady computations. Since I would imagine most people couple their pressure-based solver with a turbulence model would it not make sense to use a Chorin type method?

On a similar matter, since Fluent has ILES, URANS, and RSM options, it makes very little sense to use purely implicit FVM operators.

You should read about the NITA implemented in Fluent
