SUMMARY

The discussion focuses on setting up a Schlieren system for optical analysis in a supersonic wind tunnel project. Key components include a high-power DC mercury lamp (6 amps), a Z-type configuration, a condenser lens with a slit or round aperture, two parabolic mirrors, and a knife edge (which can be a razor blade). Recommended resources include Gary Settles' book on Schlieren techniques, and equipment suggestions include Oriel for lamps and Newport for optics. The setup allows for direct projection into a camera, producing monochromatic images.

PREREQUISITES
  • Understanding of Schlieren imaging techniques
  • Familiarity with optical components such as lenses and mirrors
  • Knowledge of high-power lamp specifications
  • Basic principles of supersonic wind tunnel operation
NEXT STEPS
  • Research the Z-type Schlieren setup in detail
  • Explore the specifications and applications of DC mercury lamps
  • Learn about the design and function of parabolic mirrors in optical systems
  • Investigate the use of knife edges in Schlieren imaging
USEFUL FOR

Aerospace engineering students, optical engineers, researchers in fluid dynamics, and anyone involved in wind tunnel testing and Schlieren imaging techniques.

hi everyone great site you guys have going...im a newbie so do excuse my stupid questions :P

Anyway...I am taking an independent study class in aerospace engineering and my friend is doing his thesis project on a supersonic wind tunnel. I am only helping out with the optical part of it and need help finding information on schlieren setups. If anyone has info regarding this topic or experience in using a schlieren setup please do let me know thanks so much! Great luck in ur studies

Look at the book from Gary Settles it is the best book on Schlieren and very simply written.
Use a Z-type setup
You need a high power lamp (DC) mercury lamp 6amps will do fine
you need a condenser lens with a slit or round aperature.
you need two parabolic mirrors
you need a knife edge (can be razor blade)
You can project straight into a camera

Lamp (Oriel)
Optics (Newport)
Camera Any will do (image will be monochromatic)

What is your budget?
