Visualization and Image Analyses of Combustion Fields

抄録

Recently, attention has been paid to the visualization and image analyses of combustion fields. For a phenomenon as complicated as combustion, visualization is most effective as a first step in model construction and the most reliable means to avoid mistakes. Details such as (a) temperature and density, (b) mixing ratio, (c) concentrations of molecules and radicals, (d) reaction and heat-release rates, (e) velocity and turbulence, (f) parameters concerning two-phase flow, (g) parameters concerning soot and particulates, (h) parameters concerning thermal radiation, (i) states in engine combustion chambers and (j) derivatives such as correlations, gradients and vectors, were targetted as objectives of the imaging diagnostics of combustion. Each item was briefly explained and its state of art was reviewed.
