My setup for this effect. Basically is use large number of particles (from particle flow) as FumeFX particle Src. A FFX Gravity helper is point toward camera slightly.
Here are my setup and detail parameters:
Generate large amount of particles (8,000) with Particle Flow.
Set your Velocity channel, so we can slow down (retime) it later.
Use Wavelet Turbulence to add details (optional)
