As in some studies the SHED was selected as the test equipment to collect and measure non-exhaust particles produced by the vehicle, the flow field distribution of non-exhaust particles in the SHED was calculated and analyzed through the CFD simulation. The collection rate of particles that could be collected at the sample port was studied. The results show that the particulate matter is distributed in a flocculent manner in the SHED. Affected by the wind speed set in the SHED, the large wind speed in front of the vehicle leads to the faster diffusion and accumulation of particulate matter to the rear of the SHED. With the increase of the wind speed of the front fan, the distribution of particulate matter is gradually uniform. After ejecting from where the tire meets the ground and hub gap, the particles spread to the rear side of the tire, and enter the wheel cover gap under the influence of the tire rolling and the shape of the tire fender. In addition, with the increase of vehicle speed, the collection rate of particulate matter also increases.
