Numerical Study on Combustion of a Liquid Fuel Droplet

Abstract

Ignition and combustion of a liquid fuel dropkt injected into a hot and highly pressurized combustor are investigated numerically, including the effect of internal circulation. Ignition delay times of dropkts predicted with internal circulation are almost the same as those from the diffusion limit model insofar as ignition taIwl near the dropkt. Combustion regime maps are drawn to classifY the dropkt combustion phenomena according to the configuration and location of the flame with respect to initial Reynolds numbers and the surrounding gas temperatures.

Single droplet ignition: Theoretical analyses and experimental findings

“…Kim and Park [71] also employed a fully elliptic, transient, axisymmetric model for both the gas and the liquid phase to investigate droplet ignition in convective, high-temperature environment. The chemistry was represented by a one-step mechanism.…”
