So the precise correlation is needed. The purposes of this study are improvement of gas flow generator and quantitative evaluation of relation between gas flow and flame. A constant volume combustion chamber which is equipped fans to generate turbulence of desired conditions was improved and used. Turbulence intensity was measured by LDV. Flame image was taken by the CCD camera with memory. Complexity of flame shape was mainly evaluated by fractal dimension. As results, improving of gas flow generator, gas flow in the chamber was found that the mean velocity was small and turbulence intensity was the same distribution in the space, and these were reproducibility. Flame complexity was mainly depend on turbulence intensity. At the range of turbulence intensity of from 0 to 4.5 m/s, tendency of fractal dimension of flame shapes is increased according to turbulence intensity. But fractal dimensions were not changed by growth of flame.}, pages = {223--228}, title = {乱流燃焼実験のための乱れ燃焼容器改善と燃焼実験}, volume = {37}, year = {2008}, yomi = {トモマツ, シゲキ and イケダ, カズアキ and ナガセ, ヨシノリ and タサカ, ヒデノリ} }
