Mechanisms of Combustion of Hydrocarbon/Alcohol Fuel Blends.
Abstract
The results reported her directly supports the U.S. Army's research and development program in alternative fuels. Liquid fuels which are homogeneous solutions of hydrocarbon and alcohol fuels are considered here. Since combustion of diesel fuel resembles that in a diffusion flame, and because turbulent nonpremixed combustion can be considered as a statistical collection of strained, laminar flamelets, studies were performed on the structure and mechanisms of extinction of strained, laminar diffusion flames and strained laminar partially premixed diffusion flames. Use of alternate fuels often results in soot formation which causes easy detection of the vehicle. Therefore, studies were also performed to clarify the chemical mechanisms of soot formation in diffusion flames. For a well controlled laboratory experiment it is essential that the composition of the fuel be known. Petroleum based fuels are often a blend of aromatics and aliphatic fuels. Therefore experiments were performed on representative fuels namely homogeneous solutions of heptane, toluene and methanol. Results were analyzed by use of asymptotic theories. The experimental apparatus is described in Chapter II. Results of the research are discussed in Chapters III - IX. Each chapter has a brief abstract describing the results.
