| Abstract(J) | 本報告では衝突噴霧火炎の流動に及ぼす壁面粗さの影響をマクロからミクロの領域における速度場情報を用いて議論した．その結果，実験で用いた壁面の粗さが粘性底層厚さより小さいことが推察され壁面上を流れる火炎流動に及ぼす壁面粗さの影響は現れなかった． Translation |
| Abstract(E) | In this report, the effect of wall roughness on the flow field of spray flames In this report, the effect of wall roughness on the flow field of spray flames impinged on the wall based on velocity information obtained over macroscopic and microscopic scales was investigated. The results indicate that the wall roughness employed in the experiments was smaller than the thickness of the viscous sublayer inside the spray, and consequently, no significant effect of wall roughness on the flow field along the wall surface was observed. |
