SBIR Phase II: Fundamental Studies of Interacting Droplet Combustion of Low Grade Fuels Using Novel Laser Diagnostics

该项目将导致一种新型诊断的发展，该诊断可以同时测量喷射火焰中单个液滴的速度，大小和温度，并测量燃烧液滴周围的气相温度场，以及涉及单个液滴，流或液滴阵列的控制实验中的速度，大小和温度。在今天的市场上没有同等的商业工具。该原型仪器将应用于高、低品位燃料燃烧过程中液滴相互作用的研究。实验将研究各种环境效应（如化学成分和温度）和流体动力学效应（如湍流和声学振荡）对液滴升温和汽化的影响。还将研究燃料液滴的瞬态加热/点火。

9412179 Bachalo This project will lead to the development of a novel diagnostic that can simultaneously measure the velocity, size, and temperature of individual droplets in spray flames, and measure the gas phase temperature filed surrounding burning droplets in addition to their velocity, size, and temperature in controlled experiments involving single droplets, streams, or arrays of droplets. There are no equivalent commercial instruments in the market today. The prototype instrument will be applied to the study of droplet interaction in the combustion of high grade and low grade fuels. the effects of various environmental effects such as chemical composition and temperature, and fluid dynamical effects such as turbulence and acoustic oscillations, on droplet heatup and vaporization will be experimentally studied. The transient heating/ignition of fuel droplets will also be studied.
