Sh. Chan et al., A COMPACT PARTICULATE DILUTION TUNNEL FOR THE CHARACTERIZATION OF DIESEL EXHAUST, PROCEEDINGS OF THE INSTITUTION OF MECHANICAL ENGINEERS PART D-JOURNALOF AUTOMOBILE ENGINEERING, 212(D4), 1998, pp. 299-310
This paper presents the design of a compact particulate dilution tunne
l used for characterizing diesel exhaust. Details of particulate mass
concentration calculations based on various methods and the estimation
s of tunnel flow temperature and relative humidity due to psychrometri
c mixing between the extracted exhaust gas and diluting air are also e
laborated.
