Combustion Kinetics of Advanced Biofuels
… potential to lower greenhouse gas emissions from combustion. Ketones are a class of biofuel candidates which are produced from cellulose. However, ketones received rather scarce attention from the combustion community compared to other classes such as, alcohols, esters, and ethers. There is little …

Shock Tube and Mid-IR Laser Absorption Study of Combustion Kinetics
… on the experimental characterization of the combustion properties of representative alternative fuels. Specifically, a shock tube and direct laser absorption systems are used to investigate the ignition and pyrolysis processes of target fuels. The research problem is motivated by concern …

Application of sensitive spectroscopic techniques to intramolecular dynamics and combustion kinetics
Modifications of Cavity Ringdown Spectroscopy (CRD) for use in the UV region are discussed. These modifications partially overcome the low sensitivity of CRD in the UV (due to lower mirror reflectivity, R - 0.99) by removal of non-exponential contributions to the ringdown decay. We have also …

Ignition Quality Tester: an alternative for characterizing the combustion kinetics of low volatility fuels, The
… are other approaches to measure the ignition kinetics of high volatility fuels, but only very limited data are available for low volatility fuels. The IQT was modified by increasing the range of temperatures it could access and by implementing a purge program so that the accuracy and …

Combustion characteristics of South African grown fuelwoods
… to be compared and ranked according to their combustion properties. Such a comparison would assist in the selection of species for woodlot development. This investigation attempted to examine the combustion kinetics of small samples in an attempt to achieve the stated aim. Initially a …

Bayesian Inference and Experimental Design of Combustion Kinetic Models
In combustion kinetic model calibration, researchers usually use experimental data to reduce the uncertainty of kinetic parameters, and Bayesian inference is the most common approach to do inverse calibration. This thesis explores two interconnected aspects of Bayesian approaches in the context of …

Evaluating Surface Mechanisms for Catalytic Combustion Of H2 and CH4 on Pd Catalysts
Applications of fuel-lean catalytic combustion for power generation and exhaust heat recovery have raised the desire for reactor optimization. Such optimization requires adequately detailed surface chemistry models to predict reactor performance over a broad range of conditions relevant to the …

Development of a generalised kinetic model for the combustion of hydrocarbon fuels
… this work is to find a generalised model for the combustion of hydrocarbons. Predicted temperature-time profiles can be obtained from detailed combustion kinetics, which can be used to derive a generalised model. If the generalised model can predict results from the detailed model it can be …

Experiment and modeling : ignition of aluminum particles with a CO2 laser
… fuel additives enable one to achieve higher combustion enthalpies and reaction temperatures. Therefore, to develop aluminum based novel and customized high density energetic materials, understanding of ignition and combustion kinetics of aluminum powders is required. In most practical …

Laminar flame propagation in mixtures with compositional stratification at small length scales
… of this behavior was a failure of the reduced kinetics to capture the increase in local reaction rate attributed to stratification, and the inability of the driving reactions to counterbalance the incoming mass flux of fuel led to destabilization of the flame front. A preliminary analysis of …

Design, Processing, and Characterization of Nanocomposites
… agent and the respective crystallization kinetics of the nanocomposite at process-relevant conditions were explored using fast scanning calorimetry. It was found that the PA 11 composite would need at least 0.5 s above 100 °C in order to crystallize via heterogeneous nucleation and that in …
