Formulation of an RP-1 Pyrolysis Surrogate from Shock Tube Measurements of Fuel and Ethylene Time Histories

Abstract

RP-1 and ethylene time histories have been measured during RP-1 pyrolysis, allowing determination of ethylene yields and overall fuel decomposition rates for RP-1. A decomposition surrogate for RP-1 was formulated using the components n dodecane, methylcyclohexane, and iso-cetane by targeting three decomposition characteristics of the fuel: compound class, overall fuel decomposition rate, and ethylene yield. Decomposition of this surrogate mixture was modeled using a newly developed detailed mechanism and the simulations are compared to the experimentally measured RP-1 and ethylene time histories. Comparisons between modeled and measured ethylene yields and overall fuel decomposition rates are also reported.
