Detection scheme and numerical simulation of noxious gas density field in the automobile indoor

摘要

Air environment of the automobile indoor has an important influence to people health, so controlling air pollution indoor of automobile arouses the widespread interest. Detecting concentration of the indoor noxious gas is precondition to make control measures. The infrared detector is used to test concentration of carbon monoxide and the carbon dioxide carbon inside of automobile, the pressure sensor to test pressure field, these test data could provide a reference for controlling air pollution, and then detection scheme has been given. According to the usual driving environment, that noxious gas flow inside of automobile is simulation analyzed, and that different ventilated pattern impact to flow of noxious gas indoor of automobile is discussed
