LiftedFlames

  • 3-D volume rendering of turbulent lifted hydrogen jet flames in heated coflow near auto-ignition limit. The coflow temperature is 750, 850, and 950 K from left to right. The stabilization mechanisms of the lifted flames are elucidated.

Turbulent lifted ethylene_air jet flame visualization

  • This is a visualization of a turbulent lifted ethylene/air jet flame in an autoignitive coflow where the particles are colored by temperature and the volume rendered is the hydroperoxy field.
