Abstract [en]

This thesis has two major purposes: (1) to investigate the impact carshave on Particulate Matter (PM) level in a limited area and (2) to demonstratethrough Computational Fluid Dynamics (CFD) the possibility toclean a limited area of PM with a system installed on a car.This thesis was performed in collaboration with Volvo Car Corporation(VCC) at Torslanda, Göteborg. All experimental data was sampledat three occasions: 24th of February, 14th of March and 3rd of June andwere compared to similar recent studies for verication. Computer calculationwere conducted in July and August with experimental data asinitial conditions. ANSYS v16.0 Fluent Meshing and ANSYS v16.0 Fluentwere used as computational software to set up and calculate the problem.The result of the experiments shows that with increased number ofcars there is an increased value of PM. It also shows that a cars ventilationsystem can be used to collect small PM. Result from CFD derivationsdisplayed that a cleaning system mounted in a car will decrease number ofPM with 5-20% in 250 seconds in a closed domain and 4% in 135 secondsin a open domain.
