- 1934 Simulation for Behavior of Hydrogen Diffusion Flame at High Speed
抄録
Assuming that flow velocity becomes faster, necking phenomenon occurs in the hydrogen diffusion flame which is watched with interest as the clean fuel. Upper stream from a necking part is laminar flow, and down stream from a necking part is turbulent flow. It is simulated by the CFD software Phoenics. In this study, a necking phenomenon was not observed in a laminar flow model and turbulence flow model analysis. However, necking phenomena observed in the analysis which assuming upper stream in the flame as laminar flow and other place as turbulent flow. The results obtained are as follows. Radius velocity toward axis increases in downstream from border below a laminar flow and turbulent flow. And flame surface moves to a core axis direction. Velocity to a center axis direction decreases in downstream from that. And flame surface spread.
