Numerical Simulation of Benzene Flow Indoor of Car-Body

The decorative material in automobile compartment sends out Benzene to cause the harm for health of the crew member, studies low of Benzene transportation in automobile compartment is precondition for formulating the control measures. In the present study we uses the multi-component model to numerical simulate status that decorative material on the chair sending out benzene, and analyze different ventilation modes impact to concentration of benzene in automobile compartment. The computation results show that benzene sent out from material on chair surface accumulates in the vehicle compartment, the air conditioning ventilates has affects greatly to the benzene transportation, when the air flow velocity increases, benzene concentration in the vehicle compartment drop universally.
