SP1-2 Chemical Thermodynamics Modeling of Vaporization and Ignition Processes in Dual-Component Fuel Spray(SP: Spray and Spray Combustion,General Session Papers)

Abstract

In order to obtain further understandings of physical and chemical characteristics of multi-component fuel spray, one-dimensional spray vaporization and ignition model has been proposed. In this model, Wakuri's momentum theory was employed to take into account the amount of air entrainment with heat quantity into the fuel spray. The temperature rise and phase equilibrium of dual-component fuel were estimated by use of SUPERTRAPP code. The ignition delay was calculated based on Livengood-Wu integral. The prediction results of this model were able to capture the trends concerning to vaporization and ignition processes observed in experiments.
