High-Pressure Combustion Research: Investigating Spherical Flame Expansion

Click For Summary
SUMMARY

The forum discussion centers on high-pressure combustion research, specifically the investigation of spherical flame expansion through high-speed imaging. The researcher, Jaap, shares images showing the breakup of flames into cells under high pressure and seeks advice on enhancing these images. Feedback from other participants, including Andy, indicates that the images already exhibit good quality, with even background illumination and contrast. Jaap is particularly interested in tips for combining schlieren techniques with high-speed photography.

PREREQUISITES
  • Understanding of high-speed photography techniques
  • Familiarity with schlieren imaging methods
  • Knowledge of combustion dynamics and flame behavior
  • Experience with image processing software
NEXT STEPS
  • Research advanced techniques in schlieren photography
  • Explore high-speed camera settings for optimal flame imaging
  • Learn about image enhancement techniques for scientific photography
  • Investigate the effects of pressure on flame characteristics in combustion studies
USEFUL FOR

This discussion is beneficial for combustion researchers, high-speed photography enthusiasts, and anyone interested in the intersection of imaging techniques and flame dynamics.

Hey Y'all,

As some of you might know I do combustion research I took high speed images of a spherically expanding flames. Look what happens at high pressure.

The flame brakes up into cells. Is there anybody that is a photo expert and that can give me advise on how to improve these images?

That image looks pretty good as-is. Nice even background illumination, good contrast, good focus. What kind of improvement are you looking for?
 
Thanks Andy,

I thought it came out OK too.

This is my first experience doing a combination of schlieren with high speed photography so I thought maybe there are people that could give me general hints etc.

Jaap
