Single droplet combustion of alternative fuels
… surplus alcohols, which are also candidates for combustion applications. This study explores both conventional and alternative fuels, including butanol and biocrude from Algal. Droplet combustion experiments were performed to analyze the combustion characteristics of the fuels. Using the …

Comprehensive Black Liquor Droplet Combustion Studies
… and recover inorganic materials. Black-liquor-droplet combustion is fundamental to understanding and potentially improving recovery boiler performance. This investigation reports comprehensive experimental data collected for a suite of five liquors. All the data were collected with …

Numerical Modelling of LOX Droplet Combustion in Hydrogen under Micro-gravity Conditions
… only water vapor as an exhaust. This makes LOX combustion research critical for improving combustion efficiency and avoiding flame instabilities in the rocket engine’s combustion chamber. The spray dispersion method is used to inject liquid oxygen into the combustion chamber, whereas hydrogen …

Ignition delay of oxygenated fuel droplets: development of a 1 second drop tower and initial 1-g test results
… there has been relatively little research in the combustion of biodiesel surrogate fuels. One fuel which has been proposed as a surrogate fuel for biodiesel is methyl butyrate. A detailed chemical kinetic mechanism for methyl butyrate has recently been developed, but it has yet to be substantially …

Numerical Investigation on Shape Impact of Deformable Droplets on Evaporation and Combustion: Method Development and Characterization
Inspired by the dilute spray regime in spray combustion, this dissertation explores the evaporation and combustion of an isolated droplet. Under a highly convective environment inside a gas combustor, due to imbalance of inertial and surface tension forces, the droplets of larger size in sprays …

Feasibility study on the utilization of soybean oil and butanol blends as an alternative fuel source for combustion applications
… fuel as a suitable alternative fuel source for combustion applications. Basic physical property testing carried out in accordance with ASTM standardized methods proved that the addition of butanol to the highly viscous soybean oil (SBO) lowered viscosity, density, and surface tension and …

Microemulsions formation, stability and their characterisations
… aqueous solution. In microemulsion applications, droplet combustion of w/o microemulsions is also studied for different surfaces (i.e. silica, oxidised Fecralloy and catalyst coated Fecralloy) in the temperature range of 313-573K. Formaldehyde and acetaldehyde are formed as intermediate combustion …

Lean Premixed Prevaporised Combustion for Microturbines
… flame stability, structures, gas emissions, and droplet behaviour in LPP combustion at conditions relevant for microturbines. The first part of the thesis examines the effect of fuel choice using zero- and one-dimensional combustion simulations. The fundamental flame properties of gaseous …

Electric field effects on chemi-ionization in droplet burning
… applied field are studied for a single isolated droplet flame under the spherically symmetric 1-D configuration. A reduced 3-step chemical kinetic mechanism is proposed to capture the production and destruction of ions inside the flame, which is then used for conducting analytical and numerical …

Auto-Ignition of Liquid n-Paraffin Fuels Mixtures as Single Droplets Using Continuous Thermodynamics
… to predict the auto-ignition time of single droplets of n-paraffin fuel mixtures using the method of continuous thermodynamics. The model uses experimental data for pure fuels to fit rate parameters for a single-step global chemical reaction equation; from this, correlations for rate …
