低レイノルズ数噴流拡散火炎の火炎形状に及ぼす重力の影響

抄録

The purpose of this study is to reveal the characteristics of jet diffusion flame under partial gravity environment. To understand the flame structure, the flame height and the surface area of jet diffusion flame were measured. The gravitational acceleration was changed 1G to 0.55G. The flame height was increased with increasing Reynolds number. The flame height H and characteristics length L were arranged by Peclet number and Froude number as H/L = 0.1188Pe^0.667Fr^-0.0861.
