POWER AND PROPULSION
nents and systems. Individuals from technical and regulatory institutions as well as individuals from OEMs, suppliers, emissions service companies, research facilities and universities will gain modern knowledge of diesel filter performance. Prerequisites Students should have some technical insight into the performance of exhaust emission aftertreatment. Attendees with science or technology background (mechanical/chemical engineering, chemistry, physics) will benefit substantially from this seminar. • Pore space and structure definitions (definitions of relevant length scales, derivation of “pore metrics” such as correlation lengths, lineal path distributions.) • Simplified representations of structures (unit cell models based on • granular, cylindrical and composite collectors.) • Flow resistance descriptors (Darcy permeability, Forchheimer • coefficient, inertial loss coefficient as functions of wall micro- geometry, cell • density, wall thickness, plug length) Filtration Concepts for Diesel Particulate Filters • Particle transport and deposition phenomena — Condensed vs. vapor phases in diesel exhaust; Diesel fractal soot aggregate basics; Diffusional transport; Thermophoretic transport; Direct interception mechanism; Inertial transport mechanism; Other phenomena (electrical effects, sticking, entrainment by exhaust flow) • Continuum filtration theory — Deep-bed filtration regime; Cake filtration regime reconstruction of filter media • True-to-the-geometry representations (digital reconstruction of filter • media, micro-flow simulation with Lattice-based techniques and discrete particle • dynamics. Examples applied to granular ceramic extruded filters, sintered metal • filters, foam filters and fibrous textile filters.) Diesel Filter Types: Materials and Configurations in Practice • Materials aspects −− Ceramics — Oxide based: Cordierite, Mullite, other (Tialite/ Aluminum Titanate, etc.); Non-oxide based: Recrystalized Silicon Carbide (R-SiC), Siliconized Silicon Carbide (Si-SiC), Silicon Nitride −− Metallics (high temperature alloys) — Sintered grains and fibers • Configurations −− Wall-flow honeycombs (square, triangular, symmetric vs. asymmetric channels.) −− Pleated, foiled (sheet-based) designs Topical Outline DAY ONE Porous Media Basics for Diesel Particulate Filters

Advanced Diesel Particulate Filtration Systems 2 Days | Classroom Seminar I.D.# C0502 As diesel emissions regulations have become more and more stringent, diesel particulate filters (DPF) have become possibly the most important and complex diesel aftertreatment device. This seminar covers many DPF-related topics using fundamentals from various branches of applied sciences such as porous media, filtration and materials sciences and will provide the student with both a theoretical as well as an applications-oriented approach to enhance the design and reliability of aftertreatment platforms. Structure, geometry, composition, performance, applications and optimizations of DPFs are some of the main topics covered in this advanced level seminar. Computer simulation techniques for analysis and optimization of DPF performance are also demonstrated. • Discuss fundamental, moderate and advanced topics on DPF structure, geometry, composition, performance, applications and optimizations • Formulate porosity, permeability, inertial loss coefficient, flow resistance descriptors, different particulate transport modes (diffusional, interceptive), etc. to develop models for predicting backpressure of DPF • Recognize different modes of particulate filtration regimes in DPF • Select, design, utilize and optimize DPF for various light duty and heavy duty aftertreatment applications • Predict, via modeling and simulations, various important DPF performance features (backpressure, peak regeneration temperature, etc.) as well as to analyze their failure modes and thus enhance the reliability of diesel exhaust aftertreatment platform designs Who Should Attend This seminar is designed for engineers, scientists, investigators and consultants involved in researching, developing, applications, designing or optimizing diesel exhaust aftertreatment compo- Learning Objectives By attending this seminar, you will be able to:
