Advanced Diesel Particulate Filtration Systems
I.D.# C0502

April 18 – 19, 2013 (8:30 a.m. – 4:30 p.m.)
www.sae.org/pdevent/C0502
This seminar covers many Diesel Particulate Filter (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.
Learning Objectives
By attending this seminar, you will be able to:
•	 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 components 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.
Topical Outline
DAY ONE
Porous Media Basics for Diesel Particulate Filters
•	 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

diameter, cell density, wall thickness); Microstructure of soot deposits
(physical and chemical properties); Soot deposition conditions and role on
soot structure: Steady state, transients, cycles; Modeling aspects
•	 Filter Regeneration
•	 Soot reactivity and structure -- Oxidation mechanisms (thermal,
catalytic, NO2); Kinetic descriptions
•	 Types of regeneration technologies -- Raising exhaust temperature
by post-injection and/or by exhaust-port injection in combination
with DOxC; Fuel borne additive-assisted regeneration; Catalyst
coating-assisted regeneration; Reactive species-assisted
regeneration (NO2-assisted, non-thermal plasma, etc.)

of DPF performance modeling; Backpressure -- Theory, insights
and lessons; Modeling: demonstrations, validations; Regeneration -Theory, insights and lessons; Modeling: demonstrations, validations
