High-Pressure Combustion Research: Investigating Spherical Flame Expansion

AI Thread Summary
High-pressure combustion research reveals that spherically expanding flames break up into cells, as observed through high-speed imaging. The researcher seeks advice on improving these images, particularly regarding the combination of schlieren and high-speed photography techniques. Feedback from other participants indicates that the images are already of good quality, with even background illumination and strong contrast. The discussion emphasizes the importance of technical expertise in enhancing photographic methods in combustion studies. Overall, the thread highlights both the research findings and the collaborative effort to refine imaging techniques.

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.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
