Exhaust Flow Performance and Pressure Drop of Exhaust Components and Systems 1 Day | Classroom Seminar I.D.# C0235 Designing more efficient and robust emission control components and exhaust systems results in more efficient performance, reduced backpressure and fuel penalty, and higher conversion efficiency. This course will help you to understand the motion of exhaust flow in both gasoline and diesel emission control components including flow-through and wall-flow devices such as catalytic converters, NOx adsorbers, diesel oxidation catalysts, diesel particulate filters as well as flow through the overall exhaust system. Discussions will also cover: flow recirculation in inlet cones, flow maldistribution and its effect on conversion efficiency in flow throughs, non-uniform particulate deposit in diesel filters, and roots of non-uniformity in flow distribution due to exhaust system design such as bends. • Describe how exhaust stream is distributed in flow-throughs in gasoline or in diesel emission components and in wall-flow components (catalytic converters, NOx adsorbers, DOC, diesel particulate filters), including in inlet cones, exit cones, bends, elbows, flow constrictions, and in other components of an exhaust system • Design exhaust systems yielding higher conversion efficiency, lower backpressure, faster light-off, and optimal performance • Design diesel particulate filter systems yielding more uniform soot distribution in filters, thus lowering both filter backpressure and its peak regeneration temperature • Describe connections between flow distribution and thermal performance such as light-off and radial and axial temperature gradients Who Should Attend This seminar is intended for engineers, managers, designers, researchers and technical associates who wish to gain deeper insight into developments and optimization of exhaust systems and components. This also includes professionals involved with catalyst and emission components and exhaust sensors. Prerequisites Any professional with a technical insight (and not necessarily a technical education) will be capable of comprehending most or all of the course content. Topical Outline • Flow-throughs (e.g. catalytic converters or NOx adsorbers) −− The basics: flow distribution; roots of and various contributors to pressure drop; effect of geometry; effect of surface area, length and diameter; role of catalyst; etc. Learning Objectives By attending this seminar, you will be able to:
