CFD Study on Effect of the Air Supply Velocity on Contaminant Transport within an Road Vehicle Cabin

Abstract:

The RNG turbulence model and species transport model were employed to simulate the dispersion of CO2 contaminant in the road vehicle cabin. Three different air supply velocities were analysed, the results indicates that CO2 concentration at middle zone is higher, CO2 concentration at seat zone is higher and easy to gather at lower air velocity. When air velocity is smaller, the height concentration appear distinctly layering. The concentration layering gradually weaken when the air supply velocity increase 5m/s. Increasing the air supply velocity the air velocity is higher than the levels and energy cost.
