Journal ArticleDOI
Deconvolution of axisymmetric flame properties using Tikhonov regularization
TL;DR: The results show that Tikhonov deconvolution provides a more accurate field distribution than onion-peeling and Abel three-point deconVolution and is more stable than the other two methods as the distance between projected data points decreases.
Journal ArticleDOI
Evaluation and Comparison of Portable Emissions Measurement Systems and Federal Reference Methods for Emissions from a Back-Up Generator and a Diesel Truck Operated on a Chassis Dynamometer
Thomas D. Durbin,Kent C. Johnson,David R. Cocker,J. Wayne Miller,Hector Maldonado,Atul Shah,Carl D. Ensfield,Christopher S. Weaver,Mike Akard,Neal Harvey,James Symon,Thomas Lanni,William D. Bachalo,Greg Payne,Greg Smallwood,Manfred Linke +15 more
TL;DR: In this study, four commercial PEMS were compared with a Federal Reference Method for measuring emissions from a back-up generator over steady-state loads and a diesel truck on transient and steady- state chassis dynamometer tests.
Journal ArticleDOI
Particle emission characteristics of a gas turbine with a double annular combustor
Adam M. Boies,Marc E. J. Stettler,Jacob Swanson,Tyler J. Johnson,Jason S. Olfert,Mark Johnson,Maximilian L. Eggersdorfer,Theo Rindlisbacher,Jing Wang,Kevin A. Thomson,Greg Smallwood,Yura Alexander Sevcenco,David Walters,Paul I. Williams,Joel C. Corbin,Amewu A. Mensah,Jonathan P. R. Symonds,Ramin Dastanpour,Steven N. Rogak +18 more
TL;DR: In this article, the authors examined multiple BC emission metrics from a gas turbine with a double annular combustor, CFM56-5B4-2P, using aggregation and sintering theory with empirical effective density relationships, a power-law relationship between primary particle diameter and mobility diameter was presented.
Journal ArticleDOI
Effective Density and Mass-Mobility Exponent of Aircraft Turbine Particulate Matter
Tyler J. Johnson,Jason S. Olfert,John P.R. Symonds,Mark Johnson,Theo Rindlisbacher,Jacob Swanson,Adam M. Boies,Kevin A. Thomson,Greg Smallwood,David Walters,Yura Alexander Sevcenco,Andrew Philip Crayford,Ramin Dastanpour,Steven N. Rogak,Lukas Durdina,Yeon Kyoung Bahk,Benjamin T. Brem,Jing Wang +17 more
TL;DR: In this paper, a modified differential mobility spectrometer was used to measure the mass and mobility of particulate matter emitted by CFM56-5B4/2P, CFM 56-7B26/3, and PW4000-100 gas turbine engine sources.
Journal ArticleDOI
A novel miniature inverted-flame burner for the generation of soot nanoparticles
Mohsen Kazemimanesh,Alireza Moallemi,Kevin A. Thomson,Greg Smallwood,Prem Lobo,Jason S. Olfert +5 more
TL;DR: In this article, the authors used lab-scale soot nanoparticle generators to study the properties of soot over a broad range of particle size distributions, and number and mass concentratio.
