CD-adapco To Demo New Approach For Simulating Diesel Particulate Filters

CD-adapco to demonstrate exciting new approach for simulating Diesel Particulate Filters at Booth 304, SAE Small Engine
Technology Conference (SETC) 2006, Nov 13-16, San Antonio Crowne Plaza Hotel, TX.

The current generation of DPFs are complex thermo-chemical devices that are subject to numerous potential failure modes,
not all of which are can be easily captured for robust vehicle calibration, and which therefore are potentially the cause
of serious warranty issues. Until recently the numerical modeling of DPFs has been prohibitively difficult, due to unique
difficulties in accurately accounting for flow physics, chemical kinetics and conjugate heat transfer. However, in response
to considerable demand from the automotive industry, CD-adapco has recently undertaken a comprehensive industrial
validation exercise to assess the DPF prediction capabilities of es-aftertreatment, their dedicated tool for the numerical
analysis of aftertreatment devices.

es-aftertreatment simulates both the DPF proper, and the Diesel Oxidation Catalyst that sits just upstream of it, through
both soot loading and regeneration cycles. By using a multiple representative channel approach es-aftertreatment captures
the full 3D detailed flow characteristics both upstream and downstream of monolith and accounts for the conjugate heat
transfer of the entire system. In each channel both the catalytic and gas phase reactions are modeled using a detailed
chemistry solver.

The validation exercise took place using a DPF geometry and experimental data kindly provided by the Ford Motor Company,
and produced generally excellent results es-aftertreatment accurately predicted the actual soot loading mechanism, by which
any non-uniformity in the initial soot distribution causes a self-correcting blockage, resulting in a fairly even distribution of soot
throughout the "dirty" filter. Using model parameters freely available in existing literature, the predictions were qualitatively and
many instances quantitatively in agreement with the pressure probe and thermal couple measurements, demonstrating that
es-aftertreatment is a powerful tool in DPF design.
