Generation of Comprehensive Surrogate Kinetic Models and Validation Databases for Simulating Large Molecular Weight Hydrocarbon Fuels.

摘要

This multi-university research initiative investigated surrogate fuel mixture methodology detailed kinetic models for representing fully prevaporized chemical kinetic/transport global combustion properties of real fuels. Concepts by which surrogate mixtures of a small number of molecular class components would emulate the global combustion properties of each specific real fuel were developed and tested experimentally by comparing surrogate mixture and real fuel behavior in a wide variety of fundamental combustion venues, including: high pressure reflected shock tube ignition delay, rapid compression machine ignition, variable pressure flow reactor reactivity/species time history, high pressure pulsed shock tube speciation, laminar premixed burning rate and strained extinction, laminar counter-flow, strained-extinction configurations, and laminar co-annular diffusive soot extinction configurations.
