Understand Particle Size Distribution with CHEMKIN-PRO

Interest in modeling particle size distributions has experienced a renaissance over the past decade.  This revitalization is a result of the development of new, innovative manufacturing and measurement technologies, which require more predictive design and analysis tools.  The need to understand particle behavior and size distributions is important in developing strategies to address soot concerns in automotive and industrial applications, and can be a key factor in the design of many chemical processes such as carbon black and titanium oxide production. Focus on the control of particle sizes of less than 2.5 microns is one recommendation of recent studies that show the detrimental impact of Particulate Matter (PM) on human health.

During this event the presenter will demonstrate how design engineers can use the Particle Tracking option in CHEMKIN-PRO to specify different chemical processes via a surface chemistry input file, and describe physical processes via the reactor model data.  Using the Particle Tracking option, the effects of different operating conditions (temperature, pressure, equivalence ratio, etc.) can be studied to determine their effect on average particle size, particle number density, and total mass/volume of particles. The ability to accurately model particle chemistry is essential in many of today’s most interesting applications.
