Spring Blossom
This photo shows three typical interaction states of twin laminar diffusion flames produced by cylindrical burners (10 mm in diameter with a 500 mL/min methane flow rate). These states include in-phase flickering (left), non-flickering (middle), and anti-phase flickering (right) modes as the flame separation distance increases. When we duplicate and rotate each image 360°, a beautiful spring garden appears, including a tiger lily, common daisy, and red spider lily.

Phoenix
In our siloxane flame study, we used a multi-element diffusion burner to generate a methane flat flame and a central siloxane (hexamethyldisiloxane, HMDSO) as shown in the photo collage. The central flame has a combination of premixed, diffusion, and sooty flame features, resembling bird feathers. Three flame images were extracted and combined into a phoenix shape and used to generate art images on the OpenArt website. The bottom image was one of the AI generated images with prompt ‘A phoenix with blue flame feathers’. The AI generated image appears to have a higher aesthetic property but also has limitations with a loss of key flame features.
