URI Multidisciplinary Research Program for FY92-FY96 on Engine Combustion
Abstract
The objectives of the Engine Research Center (ERC) are to conduct research leading to improved diesel engines, to provide trained manpower for U.S. needs, and to cooperate in technical information exchange with Army and other engine laboratories. Five projects were undertaken. One project addressed using KIVA in conjunction with experimental work to produce a computational methodology for the design of new engines. A second project worked to develop a physically based soot model for use in KIVA The results of the model were compared with ERC generated data. A third project ailed to produce a new combustion model for KIVA, which accurately portrays the physics of diesel ignition and heat release. The model is based on flamelet concepts which are enhanced by flame stretch and curvature, flame shortening, and turbulent diffusion. The model was compared to experimental data from the literature and from the ERC. A fourth project involved experimentally measuring the liquid and vapor characteristics of very high pressure injectors under pressure and temperature conditions like those found in a diesel cylinder. A fifth project worked to produce a new diagnostic system capable of characterizing a three-dimensional flow field in time. This project is still under development.
