5.3 DPM flow pattern when air flow and DPM in the same direction

Figure 16 shows the results of CFD simulations in isometric view when DPM and air flow are in the same direction (co-flow). High DPM concentration is observed in the middle of the gallery. At 50 m downstream of the vehicle, DPM particles are seen to spread over most of the middle gallery.
