Technical Session Schedule

Wednesday, April 9

Emission Control Modeling (Part 1 of 2)
(Session Code: PFL430)

Room 411 B  10:00 a.m.

Papers are invited for exhaust aftertreatment system models as well as their validation and application. Technologies covered include DOC, HC Trap, DPF, GPF, LNT, TWC, SCR, SCRF, ammonia oxidation catalysts, hybrid or combined catalysts, urea-water solution spray dynamics, and mixture non-uniformity. Modeling aspects range from fundamental, 3D models of individual components to system level simulation, optimization, variation, degradation, and control.

Organizers - Maruthi Devarakonda, General Electric Company; Thomas McKinley, Cummins Inc.; Vincenzo Mulone, Univ. Of Roma Tor Vergata; Achuth Munnannur, Cummins Inc.; Balaji Sukumar, Johnson Matthey ECT
