项目摘要

This study aims at clarificaton of opimizing combution systems for environmental protection, with special regards placed on the detailed mechanisms of combustion and pollutant fomation as well as on effective use of energy resources. Each member has carried out a survey under the allotted subject to clacify recent trends in each area. The result has been reported and discussed in depth in research meetings to find out the problems to be soived in the future.The main outcome of individual and group research work is integrated information on the following items ; mechanism of formation and destruction of nitric oxide, nitrous oxide and particulate matter in fluidized-bed combustion of pulverized coal, promotion of combustion by plasma and swirl, development of high-temperature catalyst for low NO_x during a change in fuel concentration and temperature, mechanism of formation of diesel paticulates, transition process of group combusion in premixed spray combusion, quantitative measurement of polyaromatic hydrocarbons that may promote cancerous growth, unmerical computations of non-premixed turbulent and unsteady spray combustion, direct numerical simulation of reactive turbulent flows, and so forth.In the research meetings, analyzes habe been made based on each survey to clarify the urgent problems to be solved, such as modeling and numerical analysis for steady and unsteady combustion, catalytic combustion, formation of particulate in pulverized coal combustion, direct numerical analysis of turbulent combustion, pulverized coal combustion in circulating fluidized bed, reaction model of turbulent combustion, active control of combustion, reduction of particulates in diesel engines, and formation of mutagenic substanve due to combustion.These avtivities have led to a notion that the research field for functional combustion should be limitiated and advanced not only from scientific significance but also from practical viewpoint of environmental protection.
