Which Is Better for Visualizing Jet Flow: Schlieren or BOS Photography?

[Ahsman]

hi

I have two sets of images, one schlieren and the other BOS. I need some ideas to explain the flow and see which one gives better flow properties. The flow is just a jet out of a heat gun. Any help is much appreciated

You mean which type of image gives you more info about the flow?

Thank you for the reply.

Yes. And the sensitivity of the two systems. I'll be producing mean/rms of the pixel shift and drho/dx, drho/dy but how do I then link it to schlieren images for comparison?

What is 'BOS'? I'm unfamiliar with that acronym.
