In compliance with the stringent BS-VI emission norms, control of particulate matter in diesel engine exhaust emission is currently achieved through diesel particulate filters, catalytic convertors, and baffle filters of various designs. In the present study a device comprised of a spiral duct with an increasing cross-sectional area over the length...

Context 1
... outlet pipe from the device is connected to the tailpipe of the vehicle's exhaust system (in Figure 1). The device design, as shown in Figure 2, comprises a spiral duct. The cross-sectional area of the spiral duct progressively increases over the length from the center to the outlet bend.There is a lining of heat-resistant and porous material fixed along the inside walls of the ducting. ...
Context 2
... cross-sectional area of the spiral duct progressively increases over the length from the center to the outlet bend.There is a lining of heat-resistant and porous material fixed along the inside walls of the ducting. Referring to Figure 2, the gaseous flow after entering the spiral duct moves in a circular motion. Because of the circular motion, the paths of the flow of gases and the solid and liquid particulates carried therein are influenced by the centrifugal force. ...
